MECHANICAL PROPERTIES OF KENAF/SISAL/EPOXY HYBRID COMPOSITES WITH TiO2 NANO FILLER MATERIAL

Because of their nontoxicity, low weight, biodegradability, ease of manufacturing, and appropriate mechanical strength, natural fibre composites are essential to the development of environmentally acceptable materials.To bring natural fiber-based composites up to the level of synthetic fibre composites, research has been done on kenaf/sisal/epoxy hybrid composites to enhance their mechanical properties for a wide range of applications.It has been investigated how the mechanical properties of kenaf/sisal hybrid composites are affected by titanium dioxide (TiO2) nano-filler inclusion in epoxy resin.Fillers improve the impact strength of sisal/epoxy composites, kenaf-epoxy composites and also the hybrid composite (kenaf/sisal/epoxy) when it separately examined.The tensile strength in sisal-epoxy composites, hardness in kenaf-epoxy composites are enhanced by 2%, 30% respectively.The flexural strength and moisture absorption of hybrid composites (kenaf/sisal/epoxy) are superior due to the inclusion of (TiO2) nano-fillers.
