摘要

Hybrid polymer composite can reduce the weight of the automotive component, and its specific properties are improving with synthetic fiber via the conventional route. Unlike natural fiber, synthetic fiber has the potential for high strength, toughness, and better flexural and impact toughness properties. However, these fibers are costlier than natural fibers and are not biodegradable. The main objective of this research work is to overcome the dispute over synthetic fiber. It enhanced the functional properties of the epoxy hybrid composite made with jute/kenaf/glass fibers featured with 0–3 wt% of silicon dioxide (SiO2) nanoparticles via a hand layup route configured with compression molding action. Influences of natural/synthetic fibers laminated featured with SiO2 interlayer on mechanical, moisture absorption, and thermal properties of the composites were investigated and followed by the American Society for Testing and Materials (ASTM) standard. The hybrid composite laminate containing 3 wt% SiO2 and 45 wt% treated fibers (G/J/J/K/K/K/K/J/J/G) demonstrated the best performance metrics. It exhibited a tensile strength of 102 MPa, a flexural strength of 124 MPa, a microhardness of 78 HV, and a fracture toughness of 2.35 MPa × m0.5. In addition, it showed reduced moisture absorption (30%) and improved thermal stability (71.30% at 550 °C). These advanced epoxy hybrid composites are recommended for use in automotive interior applications.
