Description of the thesis topic

In the framework of the 80 PRIME program, the 3SR laboratory is recruiting a PhD student to work on the following topic: "Towards stronger and cleaner wood than current structural composites".
Wood is a biodegradable material originated from plant biomass exhibiting very interesting specific mechanical properties. We intend to considerably increase its properties in order to make it a new material capable of competing with the best structural materials used in aeronautics or the automobile, such as composites with polymer matrices (petro-sourced) reinforced with synthetic fibers. To that extend, the wood will be "gently" delignified and de-acetylated, then shaped by compression-shearing: the objective is to re-architect the nano and meso-structures of the wood, by closing and sticking “ on demand » the lumens of wood fibers and vessels. This chemo-mechanical development process will be optimized by combining structural and chemical analyzes (NMR, FTIR, 3D imaging by X-ray nanotomography, DMA), static and dynamic mechanical tests.

Work Context

The successful candidate will be working at 3SR laboratory (https://3sr.univ-grenoble-alpes.fr/) in the CoMHet team (https://3sr.univ- grenoble-alpes.fr/fr/recherche/equipe-comhet). He will work with Dominique Saletti, Laurent Orgéas and Sabine Rolland du Roscoat. He will also work at CERMAV (https://cermav.cnrs.fr/) with Yoshiharu Nishimaya.
The 3SR laboratory is a joint research unit (CNRS, UGA, G-INP) which conducts cutting-edge research in solid mechanics and mechanics of materials
