Abstract

Nowadays, the high pollution rate in many industrialized countries requires the implementation of environmental standards in the industrial process. But most composite materials have a very low recyclability rate based on thermosetting polymers. As a result, the world of research is now interested in the development of biocomposites based on natural resources, several recent studies of which have highlighted the environmental benefits (low ecotoxicity, biodegradability). Currently, plant fibers such as flax, sisal and hemp are used and can compensate for the disadvantages of using traditional fibers. In this context, the work presented in this article is part of a project to develop biocomposite materials based on high-performance mechanical flax fibers for the manufacture of automotive parts. Hence, the current paper presents results from the experimental study as well as encountered in the literature. The objective is to understand on the one hand the state of damage and the evolution of rigidity relative to the knee point position identified in the stress tensile curves of woven fabric flax/PP and on the other hand the evolution of dissipative phenomena that may take place depending
