In research on high-efficiency and low-pollution automobile, the focus has shifted toweight-lightening of materials and carbon composite is used for improving engine and fuel efficiency. In this study, carbon composite was applied to steel-based drive shaft that requires high torque to supply power to the car engine, in order to make a shaft core that can bear the maximum rupture torque of 4,000N·m over four sessions. For Carbon Fiber Reinforced Plastics(CFRP) molding, braiding machine was used to weaving carbon fiber and the vacuum bag molding technique was applied to making the sample. To make a drive shaft core to combine with CFRP, torsion rupture test, structural analysis, X-ray analysis, and section inspection were performed before finding problems and applying relevant improvement to step-by-step cores, which led to the maximum torque value of 4,236.7N·m.
