Investigation on Mechanical Properties of Hemp Fiber-Reinforced in Cellulose Acetate Composite Compared with Other Fiber Composites

Despite their many similarities, natural fibers have superior mechanical properties to synthetic fibers, including higher ultimate strength, greater elongation, resistance to ethering, biodegradability, lightweight, and fewer toxications. The mechanical characteristics of several matrices reinforced with synthetic and hemp fibers were examined in the current paper. We made the various hemp composites using vinyl ester, cellulose acetate (CA), treated CA, and GFRP (glass fiber-reinforced polymer) with CA. Composites were examined for mechanical characteristics such as tensile, flexural, impact, and hardness. Composites have a density of 1.19 g/cm³. Hemp with vinyl ester has higher tensile strength and flexural properties than other composites, but in impact, GFRP with CA has more impact strength of nearly 400 J/m, so for making eco-friendly biocomposite for lightweight structural applications.
