ABSTRACT
In this project propose, the implementation of composite materials in helical coil suspension system is demonstrated. Previously we were using the conventional steel for helical coil. For required stiffness, the design of such springs is very bulky and costly. Then another implementation is done on the combination of conventional steel and copper and magnesium composite material. It was successful in decreasing the weight, increasing the stiffness of the system. But there are some limitations like cost, manufacturing of copper, very low stiffness of single composite spring which was not much helpful to increase the overall stiffness of the suspension system. So metal matrix composite material is used instead of fibers with combination of conventional steels. The intension behind the use of MMC is to improve overall stiffness and life of the system.
