In daily used cars the fuel used is gasoline i.e. petrol which is depleting with time. So to save this gasoline various research works are being done. In many of the research works the main criteria is to increase the efficiency of the vehicle, by increasing the mileage of the vehicle. The mileage of vehicle is mainly dependent on the power of the engine and weight of the vehicle. This project work focuses on reducing the weight of the vehicle. So the focus of this project is to replace the heavy steel leaf spring by some other material which will reduce the weight and will possess same or more strength than the steel material. In western countries in many of the aircraft applications metal parts are either replaced or repaired by composite materials or fiber metal laminates. For automobiles if we use such materials or laminates instead of metals that will help to reduce the weight as composites possess less mass density than the metals.
