Abstract: In this paper, a splitting metal mold assisted winding process, which could be used for internal grid rib reinforced cylindrical shell composite structure, was developed due to the background of the development of a certain type of composite material cabin. A scaling prototype of carbon fiber composite material was designed and formed by splitting metal mold according to the structural features. The research results show that complete shape and accurate dimension of the scaling cabin can be obtained through the use of splitting metal mold with good dimensional stability and high precision, but high labor intensity. The issues are discussed in the paper. Experiment results show that the internal grid reinforced cylindrical shell composite structure can be integrally formed by the splitting metal mold assisted winding process. Ideas on the future research composite material cabin are proposed in the paper.
