摘要
将光纤干涉仪的一个臂粘贴在复合材料梁的表面,用逐点下压的方法实现了复合材料的分层检测。试验证明:在简单支撑下分层信息可能淹没在梁本身的变形中,但在连续支撑下,能够有效地检测出材料中是否存在分层及分层的位置。试验测试和理论仿真获得了一致的结果。
The sensing arm of a optical fiber Mach-Zehnder interferometer is sticked on composite beams to detect the delamination in the beams with press method step by step. Then the experiment results show that the delamination can be effectively detected when the beam is continuously supported,and can't be detected when the beam is simply supported. The experiment test is agreement with the theory results.
