微波检测原理及其在复合材料中的应用

MICROWAVE DETECTION PRINCIPLE AND APPLICATION IN COMPOSITES

本文简要介绍了微波无损检测的原理和应用 ,利用其中的反射法对复合材料的缺陷进行检测 ,证实M .Rockwitz等人提出的针对金属介质的微波无损检测理论 ,同样适用于复合材料 ,并得出了微波在复合材料中的衰减与缺陷孔径的关系。

Microwave nondestructive detection principle and application are briefly introduced in this paper.The flaw detection was performed on composite specimens with the reflection method.It was confirmed that the microwave nondestructive detection theory which was raised by M.Rockwitz on metal was applicable to composites.The law on the relationship of void-diameter with microwave attenuation could be summarized.
