Disclosed is a CFRP drive shaft for a vehicle. According to the present invention, the CFRP drive shaft for the vehicle comprises: a connection stub which is respectively connected to a constant velocity joint respectively placed on an engine side and a wheel side, and which is formed by metallic materials; and a hollow shaft tube which includes a pressing fixing unit respectively formed on one end unit and the other end unit to be engaged with the connection stub by being pressed, and support embossed units formed on the pressing fixing unit at regular intervals in a circumferential direction, and which is formed by thermally molding carbon fiber reinforced plastic (CRFP) materials. Accordingly, the present invention is able to use the CRFP to form a shaft tube by molding the shaft tube after forming a first carbon fiber sheet layer and a second carbon fiber sheet layer to allow the fiber directions of the carbon fiber to cross each other. Accordingly, the present invention is able to reduce the weight but improve strength and durability.

    본 발명은 차량용 씨에프알피 드라이브 샤프트를 개시한다. 개시된 차량용 씨에프알피 드라이브 샤프트는, 엔진측 및 휠측에 각각 배치되는 등속 조인트에 각각 연결되며, 금속소재에 의해 형성되는 연결 스터브와, 일단부 및 타단부가 상기 연결 스터브에 압입으로 결합되는 압입 고정부가 각각 형성되고, 상기 압입 고정부에 지지 엠보싱부가 원주방향을 따라 등간격으로 형성되며, 탄소섬유 강화플라스틱(CFRP) 소재를 열간 성형하여 형성하는 중공형 샤프트 튜브를 구비하는 것을 특징으로 한다. 따라서 본 발명은 탄소섬유 강화 플라스틱(CFRP)을 이용하여 샤프트 튜브를 형성할 때 탄소섬유의 섬유질 방향성이 교차하도록 제1탄소섬유시트층과 제2탄소섬유시트층을 형성한 후 샤프트 튜브를 성형하므로, 중량을 줄이면서 강도와 내구성을 향상시킬 수 있다.
