摘要

In this study, the mechanical performance of hemp fiber reinforced epoxy composite material as environmentally friendly substitutes to typical artificial fibers used to fabricate composite materials is explored. Compression molding techniques were used to develop epoxy composite matrices reinforced with randomly distributed hemp fibers at various wt% weights ranging from 0, 10, 20, 30, to 40 wt% hemp fibers. Thorough mechanical characterization of composite samples revealed that optimum property performance of hemp reinforced epoxy composite material emerges at 30 wt% fibers, with recorded mechanical performance indicators including 43.56 MPa, 59.73 MPa, 6.79 J/cm², 91 HRRW, which represent 38.3%, 33.4%, 153.4%, 18.2% improvements over pure epoxy, respectively. However, property performance decreased at 40 wt% hemp fibers, which might be ascribed to overcrowding, which may be ascribed to insufficient infiltration or low resin/reinforcement interaction. On this basis, this study proposes hemp reinforced composite matrices as viable environmentally friendly material options for semi-structural application outcomes, which are environment friendly with no compromises in terms of material performance.
