先进复合材料的无损检测

Non-Destructive Testing of Advanced Composites

综合分析了碳纤维复合材料构件在成型和使用过程中造成的缺陷及损伤产生的原因 ,指出成型工艺原理和理论的非完美性、原材料因素、人为因素是复合材料成型过程中缺陷产生的主要原因。采用无损探伤技术对缺陷进行检测是复合材料构件质量保证的必要手段。对目前国内外用于复合材料构件的几种无损探伤方法进行了比较 ,认为超声法是复合材料常见缺陷检测的一种有效手段。并对超声检测技术的研究和应用进展进行了介绍。

Reasons of formation of defects and damages in carbon composites during manufacturing process and service are analyzed,which can be attributed to the imperfection of composites manufacturing,poor quality of raw and processing materials, and unsuitable or wrong operation of workers.Non destructive testing is an important method of insuring quality of the composites.Comparing with other non destructive testing methods,the ultrasonic inspection can be considered an effective method of checking the common defects and damages in composites,and its development of studying and application is introduced in this paper .
