Abstract:
1. A method of manufacturing a propeller shaft, which includes a transmission shaft having a metal tube and a high specific modulus composite material prepregs stacked to an inner surface of the metal tube, and yokes mounted on both ends of the transmission shaft, comprising the steps of: stacking the composite material prepregs to the inner surface of the metal tube; co-cure bonding the composite material prepregs stacked to the inner surface of the metal tube while applying pressure to the surface of the composite material prepregs; and mounting the yokes on both ends of the transmission shaft; wherein the stacking step comprises a first step of preparing composite material prepregs; a second step of wrapping the composite material prepregs around a mandrel; a third step of inserting the mandrel wrapped with the composite material prepregs into the metal tube; and a fourth step of stacking the composite material prepregs wrapped around the mandrel to the inner surface of the metal tube; and wherein a protective layer is stacked to the composite material prepregs so as to improve a damping capacity of the propeller shaft, and the composite material prepregs is wrapped around the mandrel in such a way that the protective layer is placed between the composite material prepregs and the mandrel in the second step.
