中文摘要:
      为实现大尺寸CFRP材料内部缺陷的检测,利用超声冲击共振法简单易操作的特点,使用搭载于桌面的超声共振法检测设备,对蜂窝夹层结构复合材料预置缺陷件进行检测,并实时记录检测位置和缺陷状况,验证超声共振法的可行性与准确度。搭建大尺寸复合材料构件缺陷检测平台,使用超声检测设备在试样表面匀速运动与检测,实时记录并分析实验结果,利用开发的定位记录软件得到缺陷的分布云图。实验结果表明,基于超声冲击共振法检测材料缺陷的方法操作简便、成本低廉、易上手、结果准确,可以考虑用于大尺寸复合材料内部缺陷的检测。
英文摘要:
      In order to detect the internal defects in large-scale CFRP materials, the ultrasonic testing device is set on table to test the preset defect honeycomb structure composite. During the experiments, the detection location and defect status are recorded in real-time to verify the feasibility and accuracy of the ultrasonic resonance method. The defect testing platform for large-scale composites is built using the ultrasonic testing device to move and detect on the sample surface at a uniform speed, during which results are recorded and analyzed simultaneously, and the defect distribution cloud map is obtained by the software we developed. The experimental results show that the ultrasonic impact resonance method is easy to operate and cheap with accurate results, which can be used for defects detection on large-scale composites.
