Abstract

Using fly ash and natural fibers as environmentally friendly composite materials is expected to reduce the negative impact of fly ash as industrial waste, turning it into a material with added value. One of the methods in composite manufacturing is the compression molding method. This research aims to analyze the influence of compaction loading variations on the hardness values of epoxy composites reinforced with corn husk-fly ash powder. The research begins with producing composite specimens containing corn husk powder (20% wt) and fly ash (10% wt). The specimens are pressed with compaction loading variations of 1 ton, 2 tons, 3 tons, and 4 tons. The specimens from the compression molding are then subjected to sintering treatment at 150°C for 1 hour, followed by Shore D hardness testing. The results show that the composite material's hardness increases with the compaction loading. The highest hardness is achieved at a compaction load of 4 tons with a hardness value of 80.3 SHD. The compaction process of the composite material produces a fly ash structure that undergoes agglomeration or structural densification. This phenomenon results in an increase in the hardness of the material along with an increase in the compaction loading.

Abstract

Corn husks contain a significant amount of cellulose, which contributes to enhancing mechanical properties as a reinforcing material in composites, including FML composites. Several studies on composites have shown that corn husk fibers can significantly improve bending strength due to cellulose's strong microfibril structure, which enhances the material's strength and rigidity. In this study, corn husk fibers are used as reinforcement to investigate the effect of varying fiber volume fractions on the bending strength of polyester matrix FML composites. The method employed is hand lay-up, with the composite structure consisting of 1100 aluminum skin, woven roving fiberglass fibers, and natural corn husk fibers. The volume fraction variations used are 5%, 15%, 25%, and 35%. Test results show that bending strength increases with the increase in corn husk fiber volume fraction but decreases at a 35% volume fraction. The highest bending strength is achieved at a 25% corn husk fiber volume fraction, with a value of 108.84 MPa.
