摘要:
监测碳纤维增强树脂基复合材料(CFRP)的结构损伤是一个关键问题。本文就目前国内外研究较热且应用前景较大的一类新型无损检测技术——基于CFRP导电网络的自检技术进行综述,总结了直流法和交流法的原理和技术特点,尤其是对各种检测方法适用的环境和损伤类型进行了评估。最后指出了发展出一套智能化的CFRP结构损伤自检体系所要进一步开展的研究工作。

Abstract:
Carbon Fiber Reinforced Polymer (CFRP) composites have been successfully applied to the main load-carrying structures in aircrafts, but how to monitor the structural damage is still a key problem. In this paper, a new and promising nondestructive testing technologySymbol~B@the self-sensing detection technology based on CFRP conductive network, which has become a hot field. The principles and technical characteristics of various methods including direct current (DC) methods and alternating current (AC) methods were summarized, especially evaluating the applicable environment and damage types of all kinds of detection methods. Finally, the further research for developing a set of intelligent self-sensing detection system of CFRP structural damage was pointed out.
