Design and analysis of composite leaf spring using aramid fibre

Abstract

A leaf spring is a suspension spring, commonly used to absorb the vibrationsbrought during themotion ofa vehicle due to load or road condition. The automobile sector has shown an improved concern in the replacement of metal leaf spring with composite materials due to extraordinary strength to weight ratio. This article is based on the performance comparison of leaf spring prepared from composite material which can be suitable for automobiles. By using composite fibers determinations have been made to reduce the cost and mass of the leaf spring. The composite material used here is an aramid fiber which known for its high tensile strength, high heat resistance, less abrasive and reduced weight ratio. The leaf spring is designed and analyzed. The specimens were fabricated as per the ASTM standards and testing was carried out.
