摘要

Composites made of natural fibers are widely employed in the automotive, construction, textile, and other sectors due to many desirable characteristics. In this study, kenaf and Pithecellobium dulce fibers and epoxy resin is used as the matrix are used to create hybrid composites. A number of test specimens were created by altering the fibers weight proportions. The mechanical property testing of the prepared specimens adhered to the ASTM (American Society for Testing and Materials) standards. These tests included evaluating the tensile, flexural, hardness, and impact characteristics. Additionally, the water absorption capabilities of the composites were examined. Mechanical property test findings showed that sample S5, which was alkaline treated and prepared from 60% resin, 20% Kenaf, and 20% Pithecellobium dulce fibers, had better qualities than the other samples. Both the tensile and flexural strengths of S5 is 80.59 ± 4.28 MPa and 224.19 ± 4.18 MPa respectively. A dashboard model of a car was created using the same weight proportions of the resin and fibers.
