Abstract：

For the structured part in a certain type of aircraft, and the finite element model of semi-cured GLARE laminates in the rubber pad forming process was established by finite element modeling platform ABAQUS/Explicit, and the stress-stain distributions and deformation laws of different materials were investigated during the rubber pad forming procedure, and the feasibility of GLARE formed by this technology as well as its specific process were analyzed to verify the model reliability by experiments. The results indicate that a good quality part made of GLARE laminates by rubber pad forming process can be obtained. The semi-cured part is processed by the vacuum curing to avoid the adverse factor like warpage effectively,and a qualified part that meets the production requirement is produced finally.
