THE MECHANICAL PROPERTIES OF 3D BRAID COMPOSITE ADHESIVE JOINTS
摘要
Abstract
In order to compare the efficiency of 3D braid composite repair of different type joints,the mechanical properties of step lap joint and nested joint subjected to tensile and bending load were examined experimentally by keeping the same joint length for all samples.Load-displacement curves were obtained for each type of joint by the test.Then,the strength of samples and the repair efficiency were acquired by comparing the strength of joints with intact specimens.Meanwhile,the tensile and bending damage evolution and profiles of specimens were analyzed and summarized.The test results show that the step lap joint has better mechanical properties.The repair efficiency of step lap joint under tensile load was 37.75％,and under bending load,the repair efficiency was 66.25％.The repair efficiency of nested joint under tensile load can reach 18.97％,and under bending load,the repair efficiency can reach 21.44％.关键词
