Natural Fiber composites are emerging as realistic alternatives to glass-reinforced composites in many applications like automobile industries. In composite materials, our focus is on Natural Fiber Composites because these composites are eco friendly in nature and a promising alternative for the metals because of their high strength to weight ratio and durable mechanical properties. Nowadays the natural fiber composites are used in various fields and industries even in automobiles. Our focus is mainly on Banana, Sisal, and coconut fibers because of their low weight, easily available, and low cost. So, all the fibers are extracted from the concerned plant. This book deals with the fabrication and analysis of the various combinations of with and without the moisture of Banana, Sisal, Coconut, and Glass fiber. The effect of hybridization on mechanical properties such as Tensile, flexural, impact, compression, buckling, and wear tests were explained in detail. Fractography analysis for selected samples (Tensile and Impact) was investigated using Scanning electron microscopy (SEM).
