To Evaluate Mechanical Properties of Epoxy Resin Based E-Glass / Kenaf / Husk Hybride Composite

Abstract The mechanical behavior of epoxy resin composites reinforced with combination of E-glass, kenaf and coconut husk fibers, which is a hybrid fiber, is investigated in the present study. The aim was to establish the effect of fiber length and proportion variation on tensile, flexural and impact properties. A hand lay-up process was adopted to create the composites, whereby, the epoxy resin was used as the matrix, and the fibers were added in predetermined proportions. Before being fabricated, coconut husk fibers had been treated with alkali to make them stick. Tensile, bending and impact resistance tests were done based on ASTM standardized specimens to established that hybridization is an effective solution to counteract high stiffness of E-glass fibers with toughness and ability of natural fibers to absorb the energy composites with longer kenaf and husk fibers proved to be better in terms of tensile and flexural strength, whereas coir played a significant role in impact resistance. In order to obtain optimal fiber blends, the tensile strength, flexural strength and impact strength. The results prove the fact that epoxy resin-based hybrid composites are capable of producing high mechanical performance at light weight and sustainable manufacturing. These materials are of great automotive, construction and structural potential with a viable alternative to fully synthetic composites that is environmentally responsible.
