Studies on physico-mechanical behaviour of kenaf/glass fiber reinforced epoxy hybrid composites

In this study, various treated, untreated, and treated kenaf/glass fiber composites were fabricated using epoxy resin. A portion of kenaf fibers subjected to treatment with alkali, sub-portion was taken for benzoyl peroxide potassium permanganate prior composite fabrication. This on the material undertaken achieve improved modification interface between matrix bond. glass used enhancing mechanical properties hybrid composite. The tensile strength, flexural, density, water absorption chemical resistance analyzed standard methods. FTIR conducted ascertain fibers, FESEM morphological study. results obtained showed that flexural strength from 46.45-298.3 kgf, 10.5-54.7 respectively, in samples. Chemical compared untreated both cases. density found decrease composites, less density. result revealed reaction has place reagent. Hence, due increase fiber-matrix interaction.
