Effect of fibre geometrical morphology on the mechanical properties of PolyPropylene Hemp fibre composite material

Participants : Abel Cherouat [correspondant] , Florent Ilczyszyn.

These last years, hemp fibres have been used as reinforcement for compound based on polymer in different industrial manufacturing for their interesting mechanical and ecological properties. Hemp fibres present a non-homogeneous cross section and complex geometry that can have a high effect on their mechanical properties. The mechanical properties of hemp fibres are rather difficult to determine and request a specific characterization method. In this project, micro-tensile tests coupled with numerical imaging treatments, meshing reconstitution and finite elements computations are investigated. The numerical imaging allows to define finely the hemp cross section along the fibre and aims to reconstruct a 3D hemp fibre CAD using adaptive mesh.
