Design and Fabrication of Leaf Spring by using Composite Materials - A Review

In present year’s natural fiber composite material locate 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 are coir, Aloe Vera, Palm fiber ramie, sisal, jute, banana, bagasse etc. Common matrix materials are epoxy, phenolic, polyester, polyurethane vinyl ester etc. The composites formed by fibers gained attention due to their low cost, light weight, renewability, low density, high specific strength, non abrassivity, non-toxicity and biodegradability etc. In this project, we discuss the Composite material leaf spring by using ALOE VERA with Epoxy resin. Fabrication is carried out by hand lay-up technique and to be tested, and to evaluate the Mechanical properties of leaf spring (Tensile strength, Hardness, Toughness Examination). Aim of this project is to reduce the production cost of conventional leaf springs. By using natural fiber composite leaf springs, the efficiency of the springs and performance of the cars get improved.
