In now a day the fuel efficiency and emission gas regulation of automobiles are two important issues. To fulfil this problem the automobile industries are trying to make new vehicle which can provide high efficiency with low cost. The best way to increase the fuel efficiency is to reduce the weight of the automobile. The weight reduction can be achieved primarily by the introduction of better material, design optimization and better manufacturing processes. The achievement of weight reduction with adequate improvement of mechanical properties has made composite a very good replacement material for conventional steel. To reduce vehicle weight, three techniques have been studied rationalizing the body structure, utilizing lightweight materials for parts and decreasing the size of the vehicles. In this approach by introducing composite materials into automobile industries, which is having low cost, high strength to weight ratio and excellent corrosive resistance can fulfil the requirement. The automobile vehicles have number of parts which can be able to replace by composite material, but due to the improvement of mechanical properties of composite material. It has more elastic strength and high strength to weight ratio has compared with those of steel material. So, out of many components one of the components of automobile, the leaf spring which use for carried out the whole weight of the vehicle is best option for replacement of steel material by composite materials. Leaf springs are used in suspension systems. The automobile industry has shown increased interest in the replacement of steel leaf spring with composite leaf spring due to high strength to weight ratio. Composite materials are one of the material families which are attracting researchers and being solutions of such issue. In this paper we describe design and analysis of composite leaf spring. For this purpose, a rear leaf spring for Mahindra Thar D117 CRDe Diesel leaf spring is considered. In this project we demonstrate the design and analysis of a Mahindra Thar D117 CRDe Diesel leaf spring is considered which is made up of coir reinforced polyester matrix composite and fibre reinforced polymer (S-glass/epoxy). The main objective of this project is to reduce the weight of an automobile by replacing its steel leaf spring with composite leaf spring when the load applied is constant and at the same defection compare its relative merits and demerits. The modelling of leaf-springs is done using NX -10.0 and analysis is done using ANSYS 18.1.
