Analysis of thermoplastic composite cap long truss hot stamping process

For the cap-shaped long truss structure, the hot stamping simulation calculation process is established to carry out the thermal deformation prediction of carbon fiber/nylon 6 (CF/PA6) composites, and the correctness of the numerical prediction results is verified. In addition, the effects of molding process parameters (molding temperature and holding pressure) on the rebound amount of cap long truss structure are further analyzed through numerical simulation, and the results show that: increasing the molding temperature can gradually reduce the rebound amount and increasing the holding pressure can reduce the rebound amount, but it will increase the risk of crushing. It provides guidance and basis for optimizing the hot stamping process of cap type long truss structure.
