摘要

复合材料结构雷击损伤检测已成为飞机结构健康监测(SHM)的重要任务之一。然而，由于雷击损伤机理复杂，雷击损伤检测通常采用传统无损检测技术，不适合在线监测。本文提出了一种用于复合材料结构雷击损伤监测的压电导波成像方法。首先研究了雷击对复合材料结构的损伤机理。在此基础上，提出了雷击损伤的压电导波成像方法。最后，对某碳纤维增强塑料(CFRP)复合材料板进行了ABAQUS仿真，验证了压电导波成像方法的有效性。

Lightning Strike Damage Monitoring of Composite Structures Based on Piezoelectric-Guided Waves

The lightning strike damage detection of composite structures has become one of the most important tasks of aircraft structural health monitoring (SHM). However, due to the complicated damage mechanism of lightning strikes, the lightning strike damages are usually detected with traditional NDT technologies, which is inapplicable for online monitoring. In this paper, a piezoelectric-guided wave imaging method to monitor lightning strike damages of composite structures is present. The damage mechanism of lightning strikes on composite structures is firstly investigated. Then, the piezoelectric-guided wave imaging method of lightning strike damages is developed. Finally, an ABAQUS simulation on a carbon fiber reinforced plastic (CFRP) composite plate is conducted to validate the effectiveness of the proposed piezoelectric-guided wave imaging method.
