Abstract: The application of vacuum assisted resin infusion molding in brusting-type canister cover molding was studied. The finite element analysis software was used to simulate the forward bearing capacity and impact force of the canister cover, and the simulation results were verified by three molded canister covers. The results show that the canister covers were under pressure of 0.06 MPa without damage, which was consistent with the simulation results. The average impact force of the canister covers was 1 135 N, which was 5.8% lower than the simulation prediction value.
