【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。更多还原

【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.更多还原
