Due to the excellent strength and stiffness to weight ratio, composite materials are widely used in many technical applications. The goal is to compare the stresses, deformations, and weight savings of steel and composite leaf springs. Stiffness is a design restriction. Because composite materials have a high strength-to-weight ratio and strong corrosion resistance, the automobile industry is very interested in replacing steel leaf springs with composite leaf springs. When compared to standard steel, the material chosen was glass fibre reinforced polymer (E-glass/epoxy). The design parameters were chosen and examined with the goal of reducing the composite leaf spring's weight in comparison to the steel leaf spring. Steel replacement is a hot topic in the automotive industry.and also Glass fibre reinforced polymer (E-glass/epoxy) was chosen as a replacement for traditional steel. The design parameters were chosen and examined with the goal of reducing the composite leaf spring's weight in comparison to the steel leaf spring.
