摘要: 复合材料粘接结构在制造和服役过程中会产生多种类型的缺陷，而现有无损检测方法难以快速检测此类结构。介绍了红外锁相热像法的检测理论，并结合复合材料粘接结构特性，对红外锁相热像法检测参数进行了设定。使用红外锁相热像法对产品进行现场检测试验，结果表明，该方法适用于复合材料粘接结构在生产、修补、在役过程中的质量控制。

Abstract: Different kinds of defects are found in curved composite bonding structures both in manufacturing and in serving stages. Nondestructive testing methods available now are not capable of the in-situ testing of curved composite bonding structure with high speed. Lock-in infrared thermography is characterized by non-contact, large-sized testing area, audio-visual results, et al. It is fit for the in-situ testing of curved composite bonding structure. The best testing conditions of Lock-in infrared thermography are obtained by testing of defects in composite bonding structure samples. The in-situ testing is experimented industrially. It is shown that the lock-in infrared thermography could be applied to curved composite bonding structures in manufacturing, repairing and serving stages.
