leaf spring is a vital component in a motor vehicle - particularly in car either with light tonnage or with heavy tonnage. It is needed to function both as the load buffer and as a shock absorber. This simulation was aimed to observe the strength of leaf spring due to the loading by varying the tilt angles or curvature on two different materials: composite material of 65Si7 and composite material of C17000. The declivity of leaf spring here consists of 0, 5, 10, 15 and 20°C.The result of the analysis showed that the characteristic of leaf spring using the material of composite of 65Si7 has resulted in the maximum stress compared to the leaf spring using the material of composite C17000. The characteristic of leaf spring using the material of composite C17000 has resulted in the total deformation and the strain larger than that of the leaf spring using the composite material of 65Si7. For the use of leaf spring on vehicle, it is better to use the composite material 65Si7 rather than the composite material of C17000 © 2016 Author(s).
