Finite Element Analysis of Mono Composite Leaf Spring: A Review.

Leaf springs are one of the oldest suspension components those are still frequently used, especially in commercial vehicles. In recent time it is very necessary to reduce weight while increasing or maintaining strength of leaf springs. We are using Mono composite leaf spring of glass fiber reinforced plastic (GFRP) and steel spring with similar mechanical and geometrical properties. The primary objective of this paper is to compare the load carrying capacity, stiffness, deflection and weight saving of composite (GFRP) leaf spring with that of steel leaf spring. In Automobile sector Leaf spring of steel material which is used in suspension system can be replaceable by composite material due to its high strength to weight ratio and the composite materials have more elastic strain energy storage capacity.
