The present invention relates to a structure of a car body roof rail using CFRP and, more specifically, to a structure of a car body roof rail using CFRP, which can reduce a weight, and at the same time, secure rigidity. To this end, according to the present invention, six roof rails are formed, and in the roof rails, a central portion is formed with CFRP, and both ends are formed with steel. According to the present invention, provided is a car body roof rail of which a weight is reduced, and rigidity is maintained. Moreover, the car body roof rail is easily assembled.
본 발명은 CFRP적용 차체 루프레일의 구조에 관한 것으로서, 무게를 줄임과 동시에 강성을 확보한 CFRP적용 차체 루프레일의 구조에 관한 것이다. 상기한 목적을 달성하기 위하여, 본 발명은 6개의 루프레일로 이루어지면서, 중앙은 CFRP, 양단은 스틸로 이루어지는 루프레일을 제공한다. 본 발명에 의하면, 무게를 줄이면서도 강성을 유지할 수 있고 조립이 용이한 차체 루프레일을 제공할 수 있다.
