Zusammenfassung:A bicycle frame using a carbon-fiber reinforced composite material is formed into a flat plate shape with a front part of which a thickness is the same and a rear part of which a thickness becomes narrower. The bicycle frames in a pair are coupled to face each other, thereby forming a receiving space receiving a rear wheel and supporting a bicycle. The bicycle frame using the carbon-fiber reinforced composite material includes a front surface facing a front side of the bicycle and parallel to a handlebar; a rear surface arranged to be parallel to the front surface in a side opposite to the front surface and smaller than the front surface; an upper surface connected to an upper part of the rear surface, corresponding to the rear part, and having a width becoming narrower to a rear side; a front inclined surface arranged in the front surface between the front surface and the upper surface to be inclined and having a uniform width; and a second inclined surface arranged in the rear part between the rear surface and a bottom surface to be inclined and having a width becoming narrower to a rear side. The purpose of the present invention is to provide the bicycle frame using the carbon-fiber reinforced composite material of which a manufacturing method simple. 탄소섬유강화 복합재료를 이용한 자전거 프레임은 두께가 균일한 정면 부분과 두께가 점차 감소하는 배면 부분을 구비하는 평판형상을 가지며 한 쌍이 서로 마주보도록 결합하여 뒷바퀴를 수납하는 수납공간을 형성하고 자전거를 지지한다. 상기 탄소섬유강화 복합재료를 이용한 자전거 프레임은 자전거의 정면방향을 향하며 핸들축과 평행한 정면, 상기 정면의 반대쪽에서 상기 정면과 평행하게 배열되며 상기 정면보다 작은 크기를 갖는 배면, 상기 배면의 상단에 연결되고 상기 배면 부분에 대응되며 뒤로 갈수록 폭이 좁아지는 상면, 상기 정면 부분 내에서 상기 정면과 상기 상면 사이에 경사지게 배치되며 균일한 폭을 갖는 제1 경사면, 및 상기 배면 부분 내에서 상기 배면과 상기 저면 사이에 경사지게 배치되며 뒤로 갈수록 폭이 좁아지는 제2 경사면을 포함한다.
