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。
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.
