Prof Leif E. 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.

We can measure the dilation angle of polymers!
The experimental characterisation of dilation angle of polymers is fundamental to the understanding their compressive performance. In conjunction with a journal article in Polymer Testing a snapshot video of the study carried out by Dr Gustavo Quino and the Team can be found on YouTube (kKQ6c2ByXQ0) 00:29 min.

Dr Francisca Martínez Hergueta "Impact Response of Automated Fibre Placement Advanced Placed Ply composites: An Experimental and Numerical Study"
= Video will be uploaded shortly =
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. For those unable to join on the day a video will be uploaded once it has been edited.

Professor Russell Varley "From precursor to the composite: How new carbon fibre and its composites will contribute to a more sustainable future"
The 2022 NextCOMP Annual Lecture was delivered by Professor Russell Varley on 3rd August 2022, who is part of the Leadership Team at Carbon Nexus and an invited Academic Partner with NextCOMP. Carbon Nexus works across the entire carbon fibre value chain, from spinning the precursor to producing carbon fibre tow, and of course, the carbon fibre composite. Carbon Nexus' mission is to work at the intersection of academia and industry to better understand the science and engineering of carbon fibre production and to work with industry partners to transition research into reality. This talk introduces the Carbon Nexus research facility and describes in detail the carbon fibre production process from the precursor to the carbon fibre, with specific emphasis upon the requirements for improved compression. Highlights of Carbon Nexus' recent achievements in developing a new generation of carbon fibre and its composite materials is discussed and importantly how they will contribute to creating a more sustainable future.
We would like to thank Russell once more for the lecture which was well received by all those who attended in-person and virtually.

NextCOMP Bristol researchers create film for Bristol Composites Institute Annual Conference 2021
The NextCOMP University of Bristol team members have created a film giving an overview of the project and some of their research. Attendees of the BCI Annual Conference 2021 will be able to discuss the research with the NextCOMP team at a dedicated interactive session during the event. It is an excellent opportunity for industry and academics to find out more about NextCOMP from our researchers.
