University of Bristol PhD student, Emily Leung, presented a poster and it was part of her Phd work that focused on using mirror assisted imaging techniques to detect and characterize the interface fracture through the face sheets of sandwich structures.
Emily reported that Comptest 2023 was an amazing conference, and it was great to disseminate her work to the attendees and make new connections. Senior Research Associate, Tobias Laux, was also in attendance and confirmed the amazing networking opportunity that the CompTest conference offerred.
JEC World is the global trade show for composite materials and their applications. Held in Paris, JEC World is the industry’s leading event, hosting all the major players in a spirit of innovation, business, and networking.
Principal Investigator, Professor Ole Thomsen, attended along with Professor Janice Barton to learn about new developments taking place in the composite world. With hundreds of product launches, startup cnferences, live demonstrations and networking opportunities, JEC World offers an amazing opportunity for the CerTest team to learn more about new and exciting developments that could impact or influence our research, both current and future, of the certification process and the reshaping of the testing pyramid.
CerTest Research Associate’s, Tobi Laux and Riccardo Cappello, have recently been visiting the University of Southampton from the University of Bristol. They are currently working on the development of a novel sub-component testing procedure that provides insights that cannot be obtained through traditional coupon or full-scale testing.
To achieve this, we are combining full-field imaging techniques such as Digital Image Correlation and Thermoelastic Stress Analysis to capture detailed information about the behaviour of materials under complex loading conditions.
Abstract: Recent advances in additive manufacturing with continuously-reinforced composites (AM-CC) has enabled the use of this process to realize mass-efficient, topology-optimized (TO), bioinspired structures. The consideration of the use of AM-CC-TO primary structure has raised critical questions about this material’s performance and limits of manufacturability, both linked to defects at multiple length scales. This talk will briefly cover challenges related to AM-CC-TO structure, including defect structures, topological junctions, and reconsideration of structural allowables for attritable (limited-lifetime) aircraft.

We would like to thank Jevan once more for the seminar which was well received by all those who attended, both virtually and by more than 40 people online.
Dan Zenkert is, since, 2001 a professor in Lightweight Structures at the department of Engineering Mechanics at KTH Royal Institute of Technology in Stockholm, Sweden.
Dan’s early research work was mainly focused on sandwich structures and sandwich core materials. He has also worked with cost optimisation methods for composite structures and recyclable composite materials. His current research interest is the area of so called structural batteries aiming at developing structurally load carrying materials that simultaneously store electrical energy like a battery. This research is now extended to include more functionalities to carbon fibre composites, such as sensing, morphing and energy harvesting, all properties intrinsically built into the load carrying material itself.
The presentation, on the 3rd Feb 2023, gave a brief introduction to so called structural batteries which in short are carbon fibre composite laminates that store electrical energy just like a lithium-ion battery. But more functions can be integrated using the coupling between mechanics and electrochemistry:, strain sensing, shape-morphing and energy harvesting – all built in to the material itself.
