Abstract: To solve the breakage of carbon fibre H-section annular support structure (H-section structure) during demoulding, a method of process simulation for composite has been proposed in the article. The method constructed each process division finite element model independently according to the actual process of composite structure, and connected each process division model by adhesive condition. To verify the accuracy and effectiveness of the process simulation method, the study analyzed the damage status of H-section structure during original demoulding scheme, and results corresponded exactly to the actual state. Proceed to the next step, the study optimized the demoulding scheme based on the process simulation method, the subsequent new H-section structure applying the optimized demoulding scheme all kept intact during demoulding, and the product quality fulfilled the standard of GJB 2895-B, which once again validates the effectiveness of the process simulation method.
