Compressive strength performance exploration on thick composites structures for high performance racing yachts
Dr Pierre-Yves Mechin (Dassault Systèmes, France)
Thursday 26th September 2024 at 11:00 am to 12:00 noon BST (UTC +1)
Zoom Webinar: 997 3951 0155
Passcode: NextCOMP#1Abstract: A long-term collaboration between University of South Brittany (IRDL), Dassault Systémes & marine engineering eco-system in Lorient has been established for the past 12 years with positive collaboration and results. Racing yachts are designed with dominant use of composites materials with significant anisotropy in layups and large thicknesses and high stiffness (HM400 or higher). For foils, mast & hulls, composites are often in compression (static & fatigue). The compressive strength is therefore a major topic to explore and a key parameter for performance (weight vs. stiffness). The purpose of the talk is to give an overview of the compressive strength studies & results performed with multiscale analysis considering constituents, process. This was done with a double work of experiments & numerical analysis to understand the mechanism and validate observed trends. Experiments were conducted with different resins, fibres, stackings, manufacturing process to understand the mechanism, compare materials to propose new epoxy resins and fibres combinations to increase the compressive strength. The fact that racing boats are not much defined with standard materials offer a large range of configurations to explore. Numerical studies were done to qualify an analytical model which qualify the compressive strength as a structural property, not a material value. The model was first used to get explanation on trends and more recently proposed for a general validation. The combination of CATIA & Abaqus technologies as part of the 3DEXPERIENCE Platform allow to explore the effect of the manufacturing through generation of RVE models with random fibres arrangement and waviness.
Biography: Following his PhD in Composites and work on America’s Cup projects, Pierre-Yves joined Dassault Systémes in 2017. He leads the Composites R&D team, and is involved in SIMULIA apps. Under his guidance, the Composites R&D team has delivered many key improvements impacting the complete Composites End-to-End process, ensuring a continuous digital thread. Pierre-Yves is very energetic and reactive to real-life customer requests and needs. In addition to graduating with his PhD in Material Sciences & Engineering Mechanics, Pierre-Yves worked within the Marine Engineering industry on racing yachts (60 ft boats IMOCA, VOR 70 ft, Ultime Boat, America’s Cup, & more) contributing to the structural design and material mechanical testing. Joining Dassault Systémes in 2017 as part of the CATIA Composites R&D team, Pierre-Yves’s passion and vision was two-fold. He and the CATIA Composites R&D team’s goal was first improving the accuracy of virtual simulation, accounting for the composites microstructure, including potential defects and the impact of those defects on the structure. Furthermore, the goal of extending the composites end-to-end process with integrated design, simulation, and manufacturing on the Dassault Systémes 3DEXPERIENCE Platform. Since 2020, Pierre-Yves has led the Composites R&D team developing and extending the End-to-End process (Concept, Detailed Design, & Manufacturing). At the same time, Pierre-Yves has been involved with INEOS Britannia for mast design of a racing yacht for the next America’s Cup in Barcelona (as part of the Mercedes F1 Design Team). Additionally, Pierre-Yves is dedicated to continuing research on materials, focusing on publications, experiments, and lectures with several universities in France.
We are delighted to announce this talk as part of the Next Generation Fibre-Reinforced Composites (NextCOMP) Invited Lecture Series, we do hope you can join us on the day. Please note that this lecture will be recorded and attendance approves consent.

Prof Kristofer Gamstedt "How do trees become strong in compression?"
= Video will be uploaded shortly =
Abstract: Fibre composites have seen an outstanding development during the last 50 years. These materials bear many resemblances with wood; being fibrous, composed of complementary constituents, anisotropic and light-weight. Clearly wood materials, just like unidirectional composites, are very strong in tension in the fibre direction, but significantly weaker in compression. In this presentation, we illustrate some of the approaches utilised by trees to compensate for the relatively weak compressive properties. These include beneficial residual stresses, a hierarchical structure for crack arrest, formation of reaction wood tissues in compression, and counteracting the weaker compressive strength with high tensile strength material in other parts of the tree. Some of these mechanisms could perhaps be exploited to a larger extend in the design of composite materials and components.
We would like to thank Kristofer once more for the lecture given on 14th August 2024 which was well atteneded in-person and virually. For those unable to join on the day a video will be uploaded once it has been edited.

Dr Ioannis Katsivalis "Mechanical characterisation of ultra-thin tow-based discontinuous composites"
= Video will be uploaded shortly =
Abstract: A new class of composite materials which have gained significant popularity and represent an attractive alternative to Quasi-Isotropic (QI) laminates are the so-called Tow-Based Discontinuous Composites (TBDCs). These bio-inspired composite materials are manufactured by chopping continuous prepreg tapes and randomly distributing them, effectively creating a high-performance Sheet Moulding Compound (SMC) material. The random tape distribution generates in-plane isotropy, while the use of very low tape thicknesses (below 50 µm) reduces resin pockets and increases the attainable fibre volume fractions. Using thin tapes also shifts the dominant damage mechanisms, effectively eliminating transverse tape fracture and promoting tape pull-out instead. In addition, TBDCs display increased manufacturability and reduced costs and therefore expand the design space significantly. This presentation aims to provide an overview of the experimental work conducted on the TBDC material including tensile testing, fatigue characterisation, notch sensitivity analysis, bond evaluation, and compressive testing.
We would like to thank Ioannis once more for the lecture given on 7th June 2024 which was well atteneded as part of our Next Generation Fibre-Reinforced Composites (NextCOMP) Invited Lecture Seminar Series. For those unable to join on the day a video will be uploaded once it has been edited.

Prof Zheng-Ming Huang "Strength formulae of a composite under longitudinal compression"
= Video will be uploaded shortly =
Abstract: In this talk, I will firstly present an analytical approach to the failures and strengths of a unidirectional (UD) composite under longitudinal compression. Only limited, if not the minimum, input data are required, all of which except for the initial fiber misalignment angle can be measured in advance and following existing standards. The longitudinally dominated load is decomposed into axial, shear and transverse stress components in the misaligned coordinate system. The axial component will cause the fiber to fail whereas the other mainly the shear components will bring the matrix to fail. Whichever occurs the first corresponds to the longitudinal compressive strength. If the fiber’s failure takes place ahead of the matrix’s one, the composite attains the highest compressive strength. Otherwise, a kinking failure is assumed and the compressive strength can be much lower than an expectation. Two issues are critical for achieving the compressive strength evaluation. One is the misalignment angle increment assumed in accordance with the application of the shear component, and the other is the conversion of the homogenized internal stresses of the matrix into the true values. Bridging Model and the matrix true stress theory are the fundamental tools to have achieved the purpose. Then, I will highlight an analyzing procedure for the compressive strength prediction of any fibrous composite. The analysis is begun by subdividing the fibrous composite into a series of slides, each of which contains at most one straight fiber or fiber yarn segment. The latter can be considered as a UD composite in its local coordinate system. The overall true stresses of the fiber and matrix in the fibrous composite are assembled from those of all the slides, based on which the failure detections can be carried out individually for the fiber and matrix. The smallest failure load is defined as the ultimate compressive strength of the fibrous composite.
Bio: Dr. Zheng-Ming Huang got an MS degree in solid mechanics in 1983 from Huazhong University of Science & Technology in China, and a PhD degree in materials engineering in 1999 from National University of Singapore. He was awarded a Cheung Kong Scholars Professor at Tongji University by the Ministry of Education of China in 2002. He has established a number of unique mechanics theories for composites, including a unified elastic-inelastic constitutive theory – Bridging Model, the matrix true stress theory, the interlaminar matrix stress modification method, and the incremental constitutive model for rubber-like elasticity. Based on these theories, a variety of composite failures including interface debonding and laminate delamination has been efficiently addressed with inputs almost all measurable upon existing standards and with no iteration. He has authored or co-authored more than 210 peer reviewed journal papers, 4 books, 9 book chapters and 18 patents. One of his papers has been cited more than 7100 times in Web of Science.
We would like to thank Zheng-Ming once more for the lecture given on 15th April 2024 which was well atteneded as part of our Next Generation Fibre-Reinforced Composites (NextCOMP) Invited Virtual Seminar Series. For those unable to join on the day a video will be uploaded once it has been edited.

NextCOMP Workshop on fracture toughness
On Wednesday 12th January 2024, approximately 30 academics and researchers from NextCOMP met at Imperial College London for the 5th NextCOMP workshop. Building on the success of previous workshops focusing on Initiation, and Propagation of compressive failure of composites, the Team gathered to explore the significance of measuring the fracture toughness in unidirectional fibre-reinforced unidirectional composites.
The scene opened with the first session exploring how an experimental and modelling campaign of measuring the fracture toughness aligns with NextCOMP’s primary objective “Improving the compressive strength of unidirectional fibre-reinforced composites”. Following Professor Silvestre Pinho’s insightful talk on interlaminar compression and the challenges around measuring a representative value of interlaminar fracture toughness, the Team openly discussed how experimental and modelling concepts from the proposed pre-workshop reading material could be exploited by NextCOMP.
Interactive table discussions then followed, the Team was asked to discuss and report on target questions regarding the composite’s failure mode, mode of fracture toughness, and the composite length scale that NextCOMP should be focusing on. In the last session the attendees switched up the tables, this time based on the length scale relevant to their work package which led to stimulating discussions. The tables were grouped as follows: Modelling and Testing, Design of Constituents, and Design of Structures. The table discussions were led by the researchers and the attendees were tasked to select the best concepts, comment on possible challenges, and identify future steps.
The workshop concluded with valuable feedback and the adoption of best practises. The 5th NextCOMP workshop was another success, fostering stimulating discussions, giving the opportunity for all attendees to pitch in ideas, and identify the best ways to tackle the challenges behind measuring the fracture toughness of composites.

Dr Oriol Gavaldà Diaz "Micro and nanomechanical testing of ceramics and composites"
Abstract: New structural materials rely on the micro- and nanoscale design of their microstructure to achieve the desired performance. A classic example of this can be found in long fibre reinforced composites used in aerospace, automotive or energy generation, where fibre-matrix interfaces are customised to achieve the desired strength and toughness. However, understanding the properties of these nanoscale features and their effect to the bulk failure is challenging. In this talk, I will be presenting the small-scale testing (from micro to nanoscale) that we have developed over the recent years to better understand the failure of materials and allow the design of new microstructures. I will show how we are able to test a variety of composites and ceramics and obtain nanomechanical properties such as toughness, strength and friction of fibre-matrix interfaces.
Bio: Dr Oriol Gavaldà Diaz is lecturer in the department of materials at Imperial College London (from January 2024). Oriol obtained his PhD working within the Rolls Royce University Technology Centre (UTC) in manufacturing at the University of Nottingham, looking at the behaviour of ceramic composites during a material removal process. Before re-joining the University of Nottingham as a transitional assistant professor, Oriol spent over three years as a postdoctoral research associate in the Department of Materials at Imperial exploring and developing a variety of micro- and nano-mechanical testing techniques. Currently, his main interests involve understanding the failure of materials via small scale testing (micro and nano) and advanced characterisation techniques to feed the design of the new generation of ceramic and composite materials.
We would like to thank Oriol once more for the lecture given on 10th January 2024 which was well atteneded as part of our Next Generation Fibre-Reinforced Composites (NextCOMP) Invited Lecture Series.

Laura visits the Large Hadron Collider and presents at CERN
Following the successful Workshop in Composites for High Energy Physics held at Bristol Composites Institute in November, Dr Laura Rhian Pickard visited CERN (Conseil Européen pour la Recherche Nucléaire or in English European Council for Nuclear Research) in December 2023 to present at the DRD8 Community forum on Tracking Detector Mechanics. Dr Pickard’s presentation “Composites for Tracking Detectors” was well received, by colleagues from CERN and elsewhere in the high energy physics community.
This visit was well timed as the Large Hadron Collider (LHC) beamline went into winter shutdown, allowing safe access. Dr Pickard visited ALICE - A Large Ion Collider Experiment. ALICE observes the particles produced when fast travelling lead ions collide and produce quark-gluon plasma akin to the early universe, using this information to better understand the evolution of our universe. Like all experiments within the LHC, ALICE needs composite structures to hold and cool her particle detector electronics. Very small, fine, precisely manufactured trusses sit in concentric rings around the beamline where the collisions take place, holding these detectors, with larger rings further out (shown in the figure insert).
Special thanks to María Soledad Molina González (pictured right) for organising the visit to ALICE, pictured with Dr Pickard (pictured left).
During this visit discussions on furthering the collaboration between Bristol Composite Institute, National Composite Centre, and CERN continued, with all parties keen to work together and excited to see what the future may bring. Watch this space for more information when we have it.

NextCOMP PhD Student Nicolas Darras competes in the SAMPE challenge at Advanced Engineering!
SAMPE UKIC (Society for the Advancement of Material and Process Engineering UK & Ireland Chapter) Design, Make, Test Competition Launch was hotly contested at this year’s Advanced Engineering 2023 event held at the NEC, Birmingham, UK. Nicolas Darras along with three Bristol Composite Institute (BCI) team mates Ege Arabul, Sutharsanan Navaratnarajah, and Umeir Khan enthusiastically rose to the challenge which was launched 20th September, with the finals taking place several weeks later on 2nd November.
The student teams from across the UK were tasked to design and manufacture a bridge made from composite materials using a woven hybrid flax/carbon fibre prepreg. Several design parameters were essential to meet such as the dimensions: a minimum of 625 mm long and a maximum of 60 mm high. The bridges built by each of the teams were tested in a 3-point bend test on an Instron machine amongst a throng of onlookers!
Several criteria were assessed by the judging panel such as the load-to-weight ratio, the originality of the design, and a 1-minute technical video that explained the decisions made by the teams for the design and manufacture of their specimen.
Unfortunately, Nic and his colleagues didn't win the competition, but it was a fantastic opportunity to work together with other BCI students and a unique chance to be part of the Advanced Engineering event!
Nic said, "It was really fun thinking about, designing and making the composite bridge. On the day we were quite nervous and excited, and it was a brilliant experience for all of us".

Dr Frédéric Laurin "Determination of the longitudinal compressive strength of some laminated composite materials using various classical and innovative tests"
Abstract: The present study proposed a critical analysis of the available existing tests in order to determine the longitudinal compressive strength of various unidirectional plies. The (i) standard compressive tests on uni-directional (UD) plies, (ii) additional bending tests on UD plies and (iii) an alternative tensile test on a specific lay-up that fails by fibre kinking were considered for different composite materials. The composites considered are (i) a classic aerospace carbon/epoxy material with standard ply thickness, (ii) another carbon/epoxy material with thin plies in order to study the effect of ply thickness on the strength and finally (iii) a carbon/thermoplastic material to highlight the role of the matrix on the strength studied. All these tests were highly instrumented in order to accurately determine the failure scenario and to ensure that the relevant failure mode was obtained.
In order to analyse such tests (compression, tension and flexure), a micromechanical model, associated with a damage model defined at the ply scale, has been proposed. It has been shown that the variation in the longitudinal compressive strength obtained at the UD ply scale for tensile and flexure tests is consistent when the fibre kinking is considered at the microscopic scale, which appears to be the relevant scale of analysis. In addition, the influence of the position of the plies through the thickness has also been considered for compression tests and can again be explained by the use of a micromechanical modelling.
We would like to thank Frédéric once more for the lecture given on 22nd November 2023 which was well atteneded on our first Next Generation Fibre-Reinforced Composites (NextCOMP) Invited Virtual Seminar Series.

From IMT Mines Albi to Bristol Composites Institute: Masters student Laurie-Anne's internship with NextCOMP
- "This internship was really fulfilling and enriching...I had a great time during this internship. I learned a lot both on a personal and professional level."
- - Laurie-Anne Entzmann
Masters Student Intern
NextCOMP were delighted to host Laurie-Anne Entzmann, a Masters student from IMT Mines Albi-Carmaux (École des mines d'Albi-Carmaux) for several months April-August 2023. Laurie-Anne's work focused on the development of polymer formulations leading to novel architectures designed to improve the compression properties of reinforced polymer composites. Working with Prof Ian Hamerton, Dr Rachel Board, and Dr Kirk Willicombe in resin systems, and as part of the wider NextCOMP Team, Laurie-Anne's work will be further developed in the forthcoming months.
Of her time with NextCOMP Laurie-Anne told us, "I liked being part of a team that supports and help each other, I had asked for a hand many times and I could always find people willing to help me. It gives also a lot more sense to what we are doing as it directly benefits to one another. The fact that every work package is linked to each other allowed me to have a general overview of what my work will contribute to. It also gave me the opportunity to discover many research fields of composite materials."
It was a pleasure to host Laurie-Anne who was a very valued team member during her time with us. She has now taken up another fantastic opportunity working in Japan and we wish her all the best for her future exciting endeavours!

Three undergraduate summer interns join NextCOMP
It was a real pleasure to host three undergraduate summer interns at the University of Bristol who for 7-8 weeks worked in the NextCOMP Programme exploring a range of different challenges.
We are very grateful for funding from the Faculty Industrial Liaison Office (ILO) internship scheme which supported Curtis Wong and Abdulrahman Al Hammami.
Abdul (supervised by Dr Bohao Zhang) worked on the investigation of the effect of shear strain rate on the shear behaviour of polymer matrix for carbon fibre reinforced composites and throughout the course of his internship discovered that the yielding of polymer matrix was influenced by higher shear strain rates, which can be beneficial for the finite element modelling of composite materials subjected to compression (image left).
Supervised by Dr Laura Pickard, Curtis focused his work on improving the compressive performance of pultruded rods in which he explored using different overbraiding configurations and a range of different materials (image centre).
We also thank the Henry Royce Institute for funding work undertaken by our third summer intern, Charlie Sharp as part of the Royce Undergraduate Internship Scheme. Also supervised by Laura, Charlie's project investigated structural natural material (image right), with a focus on the efficacy of natural materials for use in composite structures, particularly off shore wind turbines. As part of his internship Charlie delivered a live presentation at the Henry Royce Institute Internship conference which took place on 1st September 2023 which was an enjoyable event and an excellent development opportunity.
Throughout their time with NextCOMP our summer interns were given several opportunities to present their work and discuss their technical challenges with the wider NextCOMP Team. This lead to lots of discussion and they made some very interesting discoveries some of which will be developed further and we really enjoyed having them as part of the Team!
The last word goes to one of our summer interns who said "The most positive thing about my summer internship with NextCOMP is the experience I’ve gained with composite manufacturing and academic research... I’ve gained a better understanding of what it’s like to conduct research in the field of composite manufacturing."

CERN-tastic collaboration!
In June 2023 Dr Laura Rhian Pickard spent a week at European Organization for Nuclear Research - CERN as part of her International Strategic Fund project “Composites Solutions for High Energy Physics”, which applies a NextCOMP development to a real-world problem. The results are very promising and a paper has been submitted to a leading journal. Dr Pickard was invited to deliver a seminar during her time at CERN which was very well attended (slides are linked here), highlighting work devleoped in NextCOMP and the Bristol Composites Institute (BCI). Work is ongoing to further develop this collaboration, including a workshop which will take place in Bristol in November.
- "I was delighted when the team from CERN approached me about using my work, developed under NextCOMP, to solve a challenge for the next generation of Large Hadron Collider upgrades. Having started as a physicist the opportunity to contribute to this was a dream come true, bringing together my determination to do truly useful work in composites and the fascination of furthering our understanding of the universe. The results to date are great and have a wide range of potential applications beyond high energy physics. I had a great time during my visit and we identified multiple key areas for future collaboration between CERN and BCI, which we are now working on making a reality. Thank you to Mathéo, Diego, Francois, Soledad and everyone in the CERN composites team for a great visit and I look forward to continuing our work."
- - Dr Laura Pickard
Laura's work with CERN was made possible by her recent funding from the Career Development programme at University of Bristol. Following her successful application to the initiative, Laura undertook a three month sabbatical earlier this year enabling her focus on her career development, including attending dedicated workshops, and writing retreats to enable her to plan and write new research proposals and publications. Laura has used the time to great effect, with the CERN collaboration being one such example. NextCOMP were delighted that Laura was awarded this Career Development opportunity and we look forward to supporting Laura's future collaborative work with CERN and other partners in the forthcoming months!

Professor Leif Asp "Realisation and performance of carbon fibre based structural battery composites"
The 2023 NextCOMP Annual Lecture was delivered by Professor Leif Asp on 23rd August 2023, who is a member of the External Advisory Board for NextCOMP. This talk introduces one type of structural battery composites made from carbon fibre reinforced electrodes. Here, the negative electrode is made from PAN-based carbon fibres distributed in a structural electrolyte [1], where the carbon fibre performs three functions: acting as reinforcement, active electrode material (hosting lithium) and electron conductor. The positive electrode also utilises carbon fibres in its construction. By coating a lithium iron phosphate (LFP) rich layer onto the fibre surface the fibre acts as current collector and reinforcement. The electrodes are separated by a thin veil and impregnated by a structural electrolyte.
The effects of lithiation of the carbon fibre negative electrode on the mechanical performance of the structural battery composites are presented and discussed in depth along with manufacture and performance of the positive electrode and the structural battery composite full cell.
We would like to thank Leif once more for the lecture which was well received by all those who attended in-person and virtually.

NextCOMP Fun at the Festival of Nature!
On 17th and 18th June, the NextCOMP Team took part in the Festival of Nature organised by Bristol Natural History Consortium at Millennium Square in the centre of Bristol.
An incredibly busy Millennium Square, checkered with multiple marquees, became the hub of many fascinating nature-related discoveries. Large numbers of people attended the two-day event, from all walks of life to engage with the different activities.
The NextCOMP "Woodpeckers and Wind Turbines: How nature inspires novel materials" stand attracted a lot of attention, with visitors keen to uncover facts about and vote for their favourite "Composite Creatures" (spoiler: it was the armadillo). Visitors enjoyed interacting with artefacts such as bamboo, shells, and natural fibres as well as some manmade carbon fibres and plies. A timeline of composites through the ages introduced visitors to the many ways humans have been harnessing the power of composites since their inception to their multiple uses in society today.
The "NextCOMP Crusher" was in constant use, with visitors all struggling to create the strongest composite they could make from a jelly beam and using just two strands of pasta for reinforcement. Once constructed, attendees of all ages tested their jelly/pasta composite by applying weights until failure. This year’s Festival of Nature saw the record broken, with a massive 1 kg being achieved! Supported by our fantastic University of Bristol Public Engagement colleagues, it was a brilliant opportunity to meet and converse with curious and engaged local people.
NextCOMP's Prof Richard Trask said "What an amazing positive outreach event to engage with all ages. The Festival of Nature brings wonderful conversations around the benefits of fibre reinforced composites for society now and what we need to do for a more sustainable future. Who can resist the composite crusher – a simple test, and yet both the ‘established’ and ‘budding’ engineers and scientists are all vying to do the impossible… create a structural composite from jelly and spaghetti! Cracking fun!”

NextCOMP at The Great Exhibition Road Festival
NextCOMP hit the huge Great Exhibition Road Festival 2023 over the weekend of 17th to 18th June and totally crushed it! The Team had the chance to enthuse thousands of interested visitors about the joy and importance of composites. Attendees got to handle real composite parts, including from a Lamborghini and a fighter jet, before attempting their own model systems. Jelly beam matrices were stiffened with spaghetti reinforced before testing to destruction. The winning designer managed to hold 1.4 kg – and even put up a cash prize for anyone who could beat him (they couldn’t). The structure of the broken jelly beam was compared to the microstructure of carbon fibre epoxy fracture surfaces using a digital microscope with a fresh real human hair as a scale bar (some of the team are balder than they were before!).
The Teams efforts were highlighted by the organisers in a Tweet.
It was non-stop action for two full days over the weekend; thanks to all the support from the GERF Team, and the effort from the EPSRC-funded NextCOMP crew including Hwei Lin Khoo, Charlie Shaw, Hassan Almousa, Rupam Gogoi, Dimitrios Bikos, Gustavo Quino, Silvestre Pinho, Soraia Pimenta, and Milo Shaffer.

A lot of Jelly and a lot of Fun as Whole Primary school Community Enjoys NextCOMP Composites Outreach Activity!
Approximately 420 schoolchildren from Westbury on Trym Primary Academy, Bristol learned some fascinating things about composites and had a lot of fun using the NextCOMP Crusher activity on the 23rd March. Designed for Key Stage 2, the activity was adapted in situ so that all schoolchildren (and their teaching staff) could enjoy it, from Reception up to Year 6.
Lead by the very proactive and enthusiastic staff at the school, following a whole school assembly introducing the activity, the children were excited to manufacture and test their jelly and pasta composites and made discoveries about composites as they did so.
Enormous thanks to the Westbury on Trym Primary Academy school community for their energy and to the children for their enthusiasm. The NextCOMP Crusher Key Stage 2 Schools Activity was developed by NextCOMP team members Eleni Georgiou (PhD student on the Centre for Doctoral Training in Composites Science, Engineering and Manufacturing) and Bohao Zhang (Post Doctoral Researcher) as part of the FUTURES festival of Discovery.

Encouraging the Next Generation of Composite Engineers!
Year 4 class: "Is it hard to become a researcher?"
Answer: "Anyone can become a researcher, the most important thing is that you enjoy what you do. I didn't think I could become a researcher, but I kept just doing the things that I enjoyed. I like creating new ideas and working on things that no one else is."Eleni Georgiou (Centre for Doctoral Training student, NextCOMP) and Bohao Zhang (Research Associate, NextCOMP) recently brought composites fun to around 90 children and their teachers from Avonmouth Primary school.
They developed a very interactive "Discover and Discuss" schools activity aimed at key stage two (KS2) children as part of the FUTURES: A Festival of Discovery, supported by the University of Bristol Public Engagement. The activity introduces composite materials and provides the materials and resources for the school children to manufacture and test their own composites made from jelly and pasta using the NextCOMP Crusher experimental set-up. This resulted in a lot of questions from the school children about jelly composites, “Do you use jelly to make any of your composites?”
The activity was undertaken by three separate classes at Avonmouth Primary school (Year 3, Year 4, and Year 5). Eleni and Bohao then had the opportunity to meet each of the classes with their teacher in three Zoom calls. The school children asked some fantastic questions and were really engaged with the topic, as well as keen to find out more about research and how to become a researcher. We were delighted to be able to deliver this activity and look forward to engaging with more schools in the forthcoming months.
- "The [pupils] thoroughly enjoyed it and I believe they learnt more about composites. Fun engaging activity that allowed the [pupils] the opportunity to use their sientific skills with equipment and resources that we would not normally be able to use."

Dr Francisca Martínez Hergueta "Impact Response of Automated Fibre Placement Advanced Placed Ply Composites: An Experimental and Numerical Study"
Abstract: Low velocity impact tolerance is a major concern in the design of critical aerospace structures. Conventional composites consisting of laminated unidirectional plies possess poor impact tolerance, due to the propensity of their constituent plies to delaminate when subjected to dynamic out-of-plane loading. The resultant damage can significantly affect the residual strength of a composite. Alternative laminate architectures, e.g. 3D-wovens, non-crimp fabrics, and z-pinned composites, contain through thickness reinforcements which improve their out-of-plane response. However, the fiber crimp and fiber breakage introduced during the manufacture of these composites negatively impact their undamaged in-plane mechanical properties. A novel preform method known as Advanced Placed Ply preforming (AP-PLY) makes use of Automated Fiber Placement (AFP) technology to produce quasi-woven composites. AP-PLY laminates are more impact tolerant than conventional angle-ply composites, but retain the latter's excellent in-plane strength and stiffness.
We would like to thank Francisca once more for the lecture given on 2nd November 2022 which was well received by all those who attended.

Festival of Nature with the NextCOMP Team and Bristol Composites Institute
Members of the NextCOMP Programme Grant Team and Bristol Composites Institute enjoyed a fantastic day engaging with the public about their composites research as part of the very popular Festival of Nature on Saturday 18th June 2022. The event took place at Barton Hill Microcampus and was a brilliant opportunity for exchanging ideas with families from the local community. Conversations were focused on naturally occurring composites found in seashells, wood, cork, bamboo and living creatures and how these are inspiring future materials development. The composites timeline showed how the use of artificial composites has grown and changed our world through the ages, which prompted great conversations about how we use composites today and what we should use tomorrow. Several interactive activities were included on the stand ranging from hands-on exploration of the different concepts to a paper straw-structure building challenge. Visitors also voted for their favourite "Composite creature" in which the mantis shrimp emerged victorious after a hotly contested battle with the armadillo.
Thanks to the Festival of Nature and our Public Engagement team at University of Bristol for a thoroughly enjoyable and successful day. We are already planning for our next opportunity to engage with our local communities in the forthcoming months so watch this space!

NextCOMP were delighted to host two summer 2022 interns at University of Bristol with thanks to funding from the Faculty of Engineering Summer Internship Scheme
Supervised by Dr Laura Pickard, Lucas Lu worked on a project entitled Human Robot Collaboration Layup of Pultruded Rod Based Composites. In this project Lucas explored several methodologies for manufacturing the composites. Prof Nathan Lepora of Bristol Robotics Lab kindly loaned us the DOBOT MG400 which Lucas used to test his manufacturing methodologies.
Supervised by Dr Gustavo Quino, Harshul Jolly undertook a project entitled Simulation and Practical Testing of Pultruded Systems for Improved Compressive Performance; in which he learned modelling techniques, and simulated different geometric parameters in one of the experimental set ups currently being used for composite compression testing. Harshul also conducted experiments for one of the configurations in the Bristol Composite Institute lab.
It was a pleasure to host these two fantastic students, both of whom made some really interesting and useful discoveries throughout their internships, with their work having clearly highlighted next steps for future development. They told us that they really enjoyed working on their projects, which they said had enabled them to really accelerate their learning and develop lots of different skills, including, for example writing risk assessments, devising workplans, as well as in improving their presentation skills for their final presentations to the wider NextCOMP Team.
"It is a truly wonderful experience working with NextCOMP this summer. I have learned a lot!"
“I strongly believe this project has taught me a lot, and I will most certainly continue to use the lessons I have learned here throughout my career.”
NextCOMP Industry workshop
On Tuesday 7th June 2022 approx. 40 attendees from industry and academia met at the National Composites Centre (NCC) for the NextCOMP Industry workshop. This was an opportunity for NextCOMP industry partners to engage with the research team to hear about the research and to help define the future NextCOMP research activities.
Following an introduction and overview of the project by Prof Milo Shaffer, the first session focused on ‘Initiation of compression failure of Unidirectional composite materials’. Prof Richard Trask introduced and discussed the role of ‘damage maps for initiation of compression failure in composites’ followed by a further presentation (on behalf of Dr Soraia Pimenta) on ‘critical parameters for compression strength’. In the second session, Prof Emile Greenhalgh gave an insightful presentation on ‘propagation of compressive failure in multi-directional composite materials’ and the new challenges different stacking sequences present in initiating and containing manufacturing defects and operational damage when loaded in compression. After lunch, the final session focused on Industrial technology requirements, where the attendees were tasked to discuss and feedback on specific questions arising around how the new NextCOMP materials and design concepts could be applied to solve the challenges of today’s composite components.
The workshop was deemed a success by the NextCOMP team permitting the researchers to showcase their current project results and future ideas whilst also gaining first-hand experience of understanding and interacting with the UK’s leading composite industrial partners. Attendees reported that the workshop was useful and engaging, and an excellent opportunity to collectively debate the key questions and to gain knowledge. When asked what the most valuable aspect of the workshop had been, one industry attendee commented "Discussing the programme with others. Not only does this make a better programme, but I learned a lot."
