Framework of the project : The PhDis part of the transverse project WooFHi (Wood/natural Fiber High homogeneity/performance composite) carried by three laboratories of BourgogneFranche-Comté (LaBoMap -Cluny, FEMTO-ST -Besançon, DRIVE -Nevers). This project aims at optimizing and homogenizing heterogeneous and variable wood-based materials by layering and hybridization with natural fiber composites. The targeted structural applications concern the transport field.

Context : One of the methods to better control the mechanical properties of wooden structures is to use reconstituted materials, such as CLT (Cross Laminated Timber) or LVL (Laminated Veneer Lumber). In the latter case, thin layers of wood (veneers) are obtained by peeling a log, and assembled to obtain homogenized properties. But even in this case, the mechanical performance remains very variable compared to synthetic materials, and their use requires high safety factors. This limits their applicability in fields such as transport where the dimensioning must be done as accurately as possible in terms of weight/volume..
