Increasing competition and innovation in automobile sector tends to modify the existing products by new and advanced material products. A suspension system of vehicle is also an area where these innovations are carried out regularly. The Leaf springs are one of the oldest suspension components that are being still used widely in automobiles. Weight reduction is also given due to importance by automobile manufacturers. The conventional steel leaf spring has higher weight which also affects the fuel efficiency. Substituting composite structures for conventional metallic structures has many advantages. The main objective of this paper is the use of carbon-epoxy composite leaf spring in the place of conventional steel leaf spring and provides low cost fabrication. The Carbon-epoxy composite materials are having lower density which results into reduction in the weight of leaf spring significantly with adequate improvement of mechanical properties. The structural analysis of Carbon/Epoxy composite leaf spring has performed using FEA software (Ansys14). The result of FEA is also verified by using analytical calculations.
