Fabrication and Testing of Bio Composite Leaf Spring for Automobile Application

Automobile world has an increased interest in reduction of weight by the replacement of steel by natural fiber reinforced composites. Moreover, the composite materials have more elastic strain energy storage capacity and high strength capacity and high strength to weight ratio compared to steel. Natural fibers are emerging as low cost, lightweight and apparently environmentally superior alternatives. In present year’s natural fiber composite material locale a major role in industries like aerospace and automobile. The natural fiber is amplified by hook up with plastics. The ample availability of natural fibers such as coir, Aleo Vera, Palm fiber ramie, sisal, jute, banana bagasse etc. Common matrix materials include Vinyl ester, phenolic, polyester, polyurethane vinyl ester etc. The composites formed by fibres gained attention due to their low cost, light weight, renewability, low density, high specific strength, non-abrasivity, non-toxicity and biodegradability etc. In this paper discussed the Composite leaf spring by using banana fiber with Vinyl ester composite and to evaluate the Mechanical properties of leaf spring (Tensile strength, Hardness, Toughness Examination).
