Stage M2 - Elaboration of bio-sourced materials by ultrasonic compression

5-6 months - Starting in February/March 2025 - Today, the need to find more sustainable solutions for materials used in everyday life is opening up new avenues of research in materials science. In particular, one possible direction is to develop more sustainable processes for producing materials from biomass that could replace certain plastic products. In this context, the BioCompUS project is looking at the shaping of materials by ultrasonic compression (UCM), a process derived from ultrasonic welding (US), which enables materials to be joined together by the application of high-frequency acoustic vibration under stress. US welding is already used on an industrial scale to join metals, polymers and thermoplastic composites, but little work has been done on its use for lignocellulosic materials.
