摘　　要：分析了超声声谐振检测技术原理,采用该技术对编织石英/酚醛树脂复合材料粘接结构进行了检测技术研究。结果表明:采用所建立的超声声谐振检测装置,对于厚度为7和9 mm编织石英/酚醛树脂复合材料粘接结构可分别实现Φ10和Φ15 mm以上的脱粘缺陷检测。The ultrasonic resonant NDT technique was analytically discussed and the inspection technology of composite bond structures was studied with the developed ultrasonic resonant equipment,the result suggests that the de-bond defects more than Φ10 mm in the bond structures for the composite layer of 7 mm thick,and the de-bond defects more than Φ15 mm in the bond structures for the composite layer of 9 mm thick can be found out.
