摘要

激光超声检测技术采用脉冲激光照射的手段激励结构中的Lamb 波，可以实现远距离、非接触式的Lamb 波传播波场数据测量。针对复合材料在航空领域应用中所面临的安全和可靠性能评估问题，南京航空航天大学开展了基于激光超声技术的复合材料检测研究。采用信号处理方法提取了Lamb 波传播特征参数，进行了复合材料的损伤成像、刚度参数识别和疲劳特性评估，取得了理论和试验验证上的进展，为航空领域的复合材料无损检测技术提供了新方法。

Abstract

Laser ultrasonic technique employs pulse laser to generate the Lamb waves in the structures

achieving long-distance and non-contact Lamb wave measurement. Aiming at the problems of the safety and reliability detection in aviation composite structures

the research topics on laser ultrasonic based composite structure testing are carried out at Nanjing University of Aeronautics and Astronautics. Novel signal processing methods have been developed to extract the Lamb wave propagation characteristics

which can be used in damage imaging

stiffness reconstruction and fatigue property evaluation. The theoretical and experimental results show that laser ultrasonic technique can provide a novel non-destructive testing method for the composite structures in the aviation industry.
