Description
Summary:For this research we have built original composite materials that have a dammar-based bio-resin as matrix and are reinforced with hemp fibers. These composite materials have been subjected to tensile tests to find their mechanical characteristics and elastic constants: ultimate tensile strength, Young’s modulus, Poisson’s ratio and elongation at break. In the second part of the paper we have studied other composite samples with dammar-based resin/hemp fibers and classical composite samples epoxy/hemp fibers. By recording their free vibrations, we have determined the damping factor with respect to their mass, length, loss factor, dynamic flexural stiffness and dynamic Young’s modulus respectively. In the end, we have compared the studied samples with other composite materials reinforced with hemp fibers that have been studied in the scientific literature.
