摘要

The study deals with the mechanical and impact properties based ontensile, compressive, flexural and impacts strength of three composites ofaluminium alloy 2024-T3, kenaf fibre and three types of silica aerogel(Hamzel®, Enova® IC3100 and GEA™ 0.125). The main aim of this study isto produce an eco-friendly composites and investigate the mechanical andimpact properties of kenaf fibre-metal laminate with different types of silicaaerogel/epoxy coating. The composites were made from metal, natural fibre,silica aerogel and epoxy resin/hardener. The mechanical test was conductedusing universal testing machine that uses the ASTM standard and the impacttest conducted using a helium gas gun tunnel. The result of mechanicalproperties test shows an improvement in the strengths where Hamzel® metallaminate shows higher values of 10-20% tensile strength and 13-30% tensilemodulus than Enova® IC3100 and GEA™ 0.125 metal laminate compositesrespectively. There are negligible differences among the composites in termsof compressive strength and modulus, while a little difference was recordedon flexural strength and modulus of the three composite with Enova® IC3100metal laminate composites having the highest value due to the properties ofsilica aerogel used. For the impact strength and specific perforation energy,there is little difference in the entire composite with Enova® IC3100 metallaminate composites as the most impact strength. The study shows thatapplication of aerogel on metal and reinforced fibre will produced a highstrength composite that can be used to substitute the synthetic fibrecomponents in aircraft, automobile and in other component for industrialpurposes.
