Abstract -The present work is to emphasizing the reduction in weight of suspension system by using composite materials instead of customary leaf springs. Also improve the level of suspension by using of composite materials. The leaf spring is one of the potential items for weight reduction in automobiles as it accounts for 10% – 20% of the unsprung weight. The process is beginning with the selection of composite materials. The selection process is focused to the checking of property of the material be chosen. After the verification, the manufacturing is done by the proper methods. Then the design calculation is done for both ordinary and novel spring system. Based on the results, the design calculation for deflection and weight of springs is compared.
