Abstract

A carbon/epcxy composite drive shaft used for the power transmission of the automobiles with steel joints. Compared with the metallic drive shaft, the composite one has the weight saving of 50% with equivalent torsional strength and fatigue characteristics.In this study, the filament winding technique for the composite tube and composite/metal joining technique are estabilished. The performance test of the drive shaft is carried out. The optional condition of the sur ace roughness of the steel adherend was 1.5㎛ to 2.5㎛, and the optimal condition of the bonding thickness was 0.15mm Maximum torque and torsional stiffness of the composite drive shaft manufactured by filament winding process were found to be 210kg·m and 18.5kg·m/deg, respectively.
