【 摘 要 】

The increasing demand for materials for manufacturing products needs to be met with the development of new materials. This research aimed at developing a composite of Hibiscus cannabinus L. Fiber, corn silk, and polyester resin. In the first stage of this research, a composite of a variety of mass fractions and fiber length was made. The mass fraction used in the Hibiscus cannabinus L. Fiber: corn silk was (10%: 10%), (12.5%: 7.5%), and (15%: 5%). The fiber lengths of Hibiscus cannabinus L. Fiber and corn silk were 30, 60, and 90 mm. The method used to make composite materials was the hand lay-up method using molds. In the second stage, the composite material was tested with a tensile test. The standard used was ASTM D 638M-84 M-1. The third stage was to optimize tensile test results by using the Response Surface Methodology (RSM). The result of RSM optimization was Hibiscus cannabinus L. Fiber: corn silk composition (16%: 4%) with the fiber length of 102.4 mm, having a tensile strength of 3.65 Kg/mm2.
