Automobile world has an increased interest in reduction of weight by the replacement of steel by natural fiber reinforced composites. Moreover, the composite materials have more elastic strain energy storage capacity and high strength capacity and high strength to weight ratio compared to steel. Natural fibers are emerging as low cost, lightweight and apparently environmentally superior alternatives to glass fibers in composites. The aim of present work is to compare the Glass-Fiber-Reinforced - Composite (GFRC) leaf spring with a Natural-Fiber-Reinforced Composite/Jute-Fiber – Reinforced – Composite (NFRC/JFRC) leaf spring. Fabrication is carried by hand lay-up technique and tested. The present work carries analytical and simulated results comparison of both types of composite leaf springs. The testing was performed experimentally with the help of Universal Testing Machine (UTM) and by Finite Element Analysis (FEA) using ANSYS. Stresses and Deflection were verified with analytical and experimental results. Compared to the GFRC leaf spring, the NFRC Composite material spring has stresses much lower to steel and the spring weight is also reduced nearly to 60-70%.The NFRC leaf spring resulted reduction in deflection and stresses without compromising stiffness as experimentally and analytically.
