Determination of Impact and Hardness Properties of Neem-Kenaf Fiber Reinforced Polymer Composites

Hybrid natural fiber composites can be used to meet the present technological development and innovation needs. These natural fibers are environmentally friendly and have a better economical value. This chapter discusses the fabrication and study on mechanical characteristics of hybrid composites which consist of neem, kenaf and GFRP. Here, the composite was fabricated by hand layup technique. The arrangements of fibers are the combinations of neem and kenaf fibers placed alternatively to form the hybrid composites. For better adhesion between fibers, the matrix namely Epoxy resin LY556 and HY951 hardener is used in the ratio of 10:1. Glass fiber composites are enclosed on both the sides in order to improve the surface finish and also to avoid damages occurs during loading condition. The volumetric fraction is one-third of the total volume occupied by neem and kenaf fiber. Test result shows that hybrid natural composite has excellent impact and hardness properties.
