Design, optimization and manufacturing of monocomposite carbon/epoxy leaf spring having varying cross sections
The main objective for weight optimization is to replace a steel leaf springof a light commercial vehicle with a monocomposite leaf spring. Steel leaf spring ismodeled in Creo Parametric with the existing dimensions and analyzed for stress anddeflection using ANSYS. A composite leaf spring with varying cross sections is de-signed by using specifications of a steel leaf spring and optimized by using ANSYS.An optimized composite leaf spring is manufactured by the hand layup method withhot molding process. There was 88% weight reduction for composite leaf spring withvarying cross sections, which was the main purpose of this chapter. Fabricated leafspring is tested for the experimental validation. Experimental values were nearly thesame as that of analytical with the negligible error.
