Abstract: The automotive sector has heart enthusiastic interest for the replacement of steel leaf spring with that of glass fiber along with epoxy resin composite leaf spring. In this study the material selected is glass fibers reinforce plastic and Epoxy resin can be used which is more economical to reduce total cost of composite leaf spring. The objective is to reduce cost, weight that is capable of carrying given static external forces without failure. The constraints are stresses and displacements. In the present work the static analysis of the glass epoxy composite material is done experimentally and validates their result by using ANSYS 14.0.The stresses developed in the steel leaf spring is higher than that of composite leaf spring. According to the previous literature of SAE it is predicted that the fatigue life of steel leaf spring is up to 106(10, 00,000) cycles. In this work with help of ANSYS workbench 14.0 the fatigue life of the glass epoxy composite is predicted it is up to 109(1000000000)cycles which are higher than steel leaf spring. The weight of the composite leaf spring nearly 64.28%l lower than that of the steel leaf spring.
