For optimal torque the transmission to differential required lighter of driveshaft, this aims to minimize the losses of powers. The previous studies, fourteen layers of carbon fiber/epoxy were needed to produce a driveshaft capable of torque from a vehicle with an engine capacity of 1300 cc. the efficiency of fuel use will be more optimal if the driveshaft has a lighter weight. this research was conducted to find the best orientation winding angle of carbon fiber direction, layer stacked and the number of layers. In this study is using the composite carbon fiber/epoxy as a drive shafts for rear-wheel drive vehicle with engine capacity is 1.300 cc has maximum 120 N.m is torque. The length is 785 and is 60 mm diameter were taken from reference SM45C steel drive shaft. The design is using by finite element analysis (FEA) simulation method. Furthermore, the manufacturing process of specimen composite drive shaft to according simulation results recommendations. Configuration of winding angle and stacking sequence is found the best is 45/45/0/0. The winding angle 450 has a good torque characteristic. The winding angle 450 are arranged on the hoop of drive shaft, because the stress is greatest torque occurs on outer side. The winding angle 00 have a better ability on tensile and bending conditions. The use of drive shaft composite carbon fiber/epoxy can reduce weight to 88%.
