Effect of the fibre morphology and aging conditions on the mechanical properties of hemp fibers
Résumé
In this study, digital treatment method was developed in order to reconstruction of the 3D CAD of hemp fibre geometry. The influence of each aging condition (moisture, heat and UV aging) on the mechanical properties of hemp fiber is investigated by micro tensile tests. Different hemp fibre morphologies was presented and discussed. The results showed a high impact of the hemp fibre morphology on their mechanical properties (Young modulus, maximum stress and failure strain). The influence of aging conditions on the mechanical properties of hemp fibers is also investigated.
