Strength and Fracture of Unidirectional Green Composites Reinforced by Hemp Fiber
In this paper, unidirectional Manila hemp fiber-reinforced thermoset composites were fabricated and their mechanical properties and fracture behavior were also investigated. Both unsaturated polyester resin and epoxy resin were used as matrix polymer. The tensile strength and Young’s modulus of the epoxy-based composites reached the maximum of 520 MPa and 17 GPa at the fiber volume fraction of 72%, respectively. Such excellent mechanical properties are seemed to be derived both from a good permeability of resin into hemp fiber bundles and from enough stress transfer between fiber and matrix.
