摘要：
Drop hammer impact tests on the Fibre Reinforced Resin-Based composite stiffened panels are used to make low velocity impact damage. And then shearing experiments on impacted specimen and intact ones are conducted to obtain the buckling load and failure load. Test results of impacted specimens and intact ones are compared to analyse the effect of damage on the carrying capacity of the structure. The results show that there is no obvious buckling during the tests for two kinds of panels. But the low velocity impact damage on the panel can reduce the failure load of the structure a lot. The failure modes mainly contain damage of four corners, cleaving of skin and deformation of specimen and so on. The experimental results offer some valuable references to engineering application of the structure.
