Abstract

A composite is a material made from a combination of two or more materials. The purpose of this study was to determine the feasibility of a reinforced configuration of coco fiber. The method of making this composite used the hand lay-up method or an open mold process. The test results of the coir fiber composite had an actual density value of 60% fiber and 40% resin composition of 1.19 g/cm³ and the lowest porosity value of 0.58% in the random arrangement fiber impact test specimen. The best value of impact toughness was found in the composition of 50% fiber and 50% resin of 271,311.29 J/m² in straight fiber specimens with ductile mechanical properties. This value was much higher than the impact toughness of SNI 18111-2007 helmet material of 9,720 J/m². Based on these results, the composite material, polyester resin reinforced with coconut fiber, is suitable as an alternative material in the manufacture of SNI helmets when viewed from the value of impact toughness and tensile strength.
