Abstract:

提出一种光学干涉谱域相位对照B扫描,透视测量透明或半透明玻璃纤维/树脂复合材料内部离面位移的方法。针对玻璃纤维增强树脂基复合材料,设计了一种由树脂层模仿树脂基体、气隙层模仿裂缝气隙、玻璃层模仿玻璃纤维构成的树脂-玻璃复合构件,然后以此复合构件作为标定和量化系统的标准件进行实验研究。通过对平滑或散斑表面树脂-玻璃复合构件分别进行加载前后干涉光谱的两次拍摄,完成构件内部切面的离面位移测量,测量速度快。该系统的视场范围为3.5mm、轮廓测量分辨率为±26.6μm、离面位移测量精度为±0.1μm、测量深度为2.66mm。该方法在玻璃纤维增强树脂基复合材料力学性能测量和无损检测领域应用前景良好。
