Now days the foremost important problem among the automobiles are fuel efficiency and emission gas regulation. The load of car is very important then the fuel efficiency of the car. So By decreasing the rear load of automobiles is healthier than that of sky rocketing the fuel efficiency. The aim of this project work is optimization of weight by employing of the mono spring within the automotive vehicles. In line with the ASTM standards, style, analyze, fabricate and testing of mono composite spring is that the main goals of the project. The rear load of the machine element is feasible to scale by the material, with no reduction within the load carrying capacity. FRP spring even have excellent fatigue resistance and sturdiness. During this project work, the composite spring is made by the vacuum resign infusion composite fabrication Process. The specimen is tested for the static load carrying capacity on universal testing machine. Here, the steel spring has higher stresses compared to the fiber reinforced composite spring. The fiber reinforced composite spring is a smaller amount than the steel spring. Hence the fuel saving is obtained. This make countries energy independent, hence the fuel is saved and fuel is produced. The optimization of the spring geometry is that the most given consideration. the most target of the project was to induce the mono spring with minimum load, therefore the spring is must capable of carrying the given static external forces or load without failure. Stresses and displacement were look constrains. The specimen is tested for the static load carrying capacity on universal testing machine.
