A Review on Composite Material-Based Leaf Spring for Automotive Vehicle

Abstract

Today's greater competition and innovation in the automobile industry tend to modify current items or replace them with newer models made of advanced materials. Another place where these kinds of changes are often made is the suspension system of any vehicle. There are several attempts made to increase user comfort. Automobile vehicles employ leaf springs as their primary suspension mechanism. Periodically, the leaf spring design will be improved by switching from standard steel to composite material. In general, composite materials are employed primarily in a variety of industries, including the marine, automotive, and aerospace industries. Due to their excellent strength, they are frequently employed in low-weight applications and as a cheaper alternative to metals. This essay provides an overview of the literature on the suitability of composite materials for car leaf springs. It contrasted with a typical leaf spring and covers the study and design of composite leaf springs. Software like CAITA, Creo, etc. is used by certain authors to design leaf springs, while ANSYS software is also used to analyze leaf springs. According to many research studies, composite leaf springs are thought to offer advantages over standard mono and multi-steel leaf springs in terms of weight, stresses, vibration, expanding strength, exhaustion life, and riding comfort.
