The invention provides a carbon fiber field bicycle and a method, and relates to the technical field of field bicycles, the carbon fiber field bicycle comprises a bicycle frame integrally formed by curing carbon fibers, and the bicycle frame comprises a front triangular structure composed of an upper tube, a lower tube and a seat tube and a rear triangular structure composed of a seat supporting tube, a transmission supporting tube and a seat tube; the fiber layers corresponding to the pipe fittings forming the front triangular structure are distributed in the axial direction of the corresponding pipe fittings, the fiber layers in two different directions are distributed on the saddle branch pipe, the fiber layers in three different directions are distributed on the transmission branch pipe, and the fiber layers in four different directions are distributed on the five-way part. The bicycle frame integrally formed by the carbon fibers is adopted as a main body structure, and the distribution of fiber layers at the positions of all composition pipe fittings and key nodes of the bicycle frame is optimized, so that the carbon fibers are continuously distributed, and the strength of the field bicycle is improved.

    本发明提供一种碳纤维场地自行车及方法,涉及场地自行车技术领域,包括由碳纤维一体固化成型的车架,车架包括由上管、下管、座管组成前三角结构和由车座支管、传动支管、座管组成的后三角结构,组成前三角结构的管件所对应的纤维层沿其对应管件的轴向分布,车座支管分布有相异两个方向的纤维层,传动支管分布有相异三个方向的纤维层,五通处分布有相异四个方向的纤维层,针对目前场地自行车强度和刚度较差的问题,采用碳纤维一体成型的车架作为主体结构,并优化车架各个组成管件及关键节点位置的纤维层分布,使碳纤维连续分布,提高场地自行车的强度。
