Abstract: In recent years, with the concept of the lightweight automotive deeply rooted, CFRP is expanding the range of applications in the automotive filed. The automotive drive shafts is very important in car. It has so significant huge economic value that we designed it by using composite materials both for its theoretical research and engineering applications and the environment and enhance the upgrading of domestic automobile manufacturing industry in transition. In this paper, we first make the finite element model, then, the basic factor that is winding angle, winding layers, winding thickness of the drive shaft. The method of optimization is ANSYS parameter design language and SUBP and first-order optimization method of ANSYS. The purpose of this paper is to optimize automotive drive shaft and make its winding angle and winding thickness better and make it lighter, higher strength.

Key words: filament-winding, composite material, drive shaft, optimization design
