Investigation on Bio-Sourced Textile Reinforcement for Composite Material Based on Sisal Moroccan Yarns

The main objective of this paper aims at investigating the potential use of sisal yarn into composite material despite the inherent variability of properties of natural resources. A multi-scale approach of the behavior of sisal fiber woven reinforcements is conducted to understand and evaluate the different properties of woven reinforcements. At the yarn scale, a piezo-resistive sensor yarn was developed to assess deformations and stress concentrations in-situ in order to understand the material behavior during the weaving of woven reinforcements fibrous for bio-sourced composite materials. At the fabric scale, 2D woven reinforcements are developed based on a conventional weaving process. The production and characterization of composite sheets based on 2D woven reinforcements show the potential of sisal fiber woven reinforcements compared to natural fiber woven reinforcements from literature.
