摘要
Abstract
The tensile test was carried out before and after the repairing of the glass fiber-aluminum laminates with presetting hole defects.The influence of the load on the tensile displacement during the stretching process was discussed,and the influence of the reinforcing sheet on the tensile strength of the material was analyzed.The results show that all the glass fiber-aluminum laminates have experienced the yield stage,the repaired laminates exhibit a more obvious yield phenomenon,and the load fluctuates greatly before the damage.The ultimate strength of the repair rate was 17.7％,13.2％,20.6％,respectively,for the aminates,containing 6 mm,10 mm,12 mm hole defects.Due to the repairing plates,the laminates showed double fan damage in the fracture position after the tensile fracture.The damage form of the repairing plates was shear failure of the film,which occurred on the surface of the aluminum alloy.关键词
