Abstract
Vacuum assisted resin diffusion molding (VARIM) is a low-cost manufacturing technology. In order to reduce the manufacturing cost of canister cover, VARIM was applied to the forming of truncated pyramid type canister cover. The finite element software was used to simulate the internal failure pressure and reverse pressure bearing capacity of the truncated pyramid type canister cover, and three canister covers were made for experimental verification. The results show that the physical test results were in good agreement with the simulation results. The canister covers were well under 0.02 MPa reverse pressure without damage, which was consistent with the simulation results. The average internal failure pressure of the canister covers was 0.055 MPa, which was 7.2% higher than simulation prediction value.
