复合材料胶接缺陷的红外热像检测

简要介绍了红外热像的检测原理，并用红外热像方法对铝蜂窝铝蒙皮复合材料较易出现的胶接缺陷进行检测，结果表明红外热像方法是检测复合材料胶接缺陷的快速、有效方法。不同性质缺陷的最佳检测时间不同，对于铝蜂窝铝蒙皮结构复合材料蒙皮的各种脱粘缺陷，检测速度都高于每分钟两屏。实现被检工件快速、方便、自动化的加热方式，加热源和热像头的同步自动扫查以及智能化地识别各种缺陷是今后红外热像检测发展的重要方向。

Evaluation of Composites Bonding Defects by Infrared Imaging Testing

Principle of infrared imaging testing is briefly presented and bonding defects of honeycomb aluminum composites are inspected by infrared imaging technique.Testing results show that infrared imaging is a rapid, effective testing method for detection of bonding defects in composite materials. The optimal testing time for different defects is different,and the testing speed is higher than two screens per minute for all bonding defects of honeycomb aluminum composites. A rapid automatic heating mode, a automatic synchronous scanning of heating source and infrared detector, and a intelligent defect identification system will be the important developing aspects of infrared imaging testing technique.
