The aircraft lightning environment consists of four lightning current components with different parameters, which are known as lightning components A, B, C and D. The lightning damage of aeronautic carbon fiber reinforced polymer laminates subjected to multiple continuous sequential lightning current components with different timing combinations was experimentally evaluated. The experimental results indicated that the carbon fiber reinforced polymer laminates suffered serious lightning damage, including carbon fiber fracture, resin pyrolysis and delamination. Through an analysis of the lightning damage properties of carbon fiber reinforced polymers, the influential factors and evaluation methods of the lightning damage in carbon fiber reinforced polymer laminates were studied. Because the lightning damage evaluation method under a single lightning impulse was found to be inapplicable for the multiple continuous lightning strikes, a multi-factor evaluation method was proposed. In the multiple continuous lightning strike test, the damage depth was found to be closely related to lightning components A, B and D and could be estimated based on the amplitudes and rise rates of the applied lightning components. Increases in the damaged area after a lightning strike were driven by lightning component C due to its substantial thermal effects. The damaged area was evaluated on the basis of the parameters of the electrical action integral and the transfer charge. The research on the evaluation methods for carbon fiber reinforced polymer laminate lightning damage presented herein may provide experimental support and a theoretical basis for studying the lightning effect mechanism and optimizing material formulations, manufacturing processes and structural designs to achieve performance improvements for carbon fiber reinforced polymer laminates in the future.

不同电流组分组合多次雷击下碳纤维增强聚合物雷击损伤评价方法
飞机雷电环境由四个不同参数的雷电流分量组成,分别称为雷电流分量A、B、C和D。 航空碳纤维增强聚合物层压板受到多个不同时序组合的连续连续雷电流分量的雷击损伤进行了实验评估。实验结果表明,碳纤维增强聚合物层压板遭受了严重的雷击损伤,包括碳纤维断裂、树脂热解和分层。通过对碳纤维增强复合材料雷击损伤特性的分析,研究了碳纤维增强复合材料层合板雷击损伤的影响因素及评价方法。针对单次雷击下的雷击损伤评价方法不适用于多次连续雷击,提出了多因素评价方法。在多次连续雷击试验中,发现损伤深度与雷击分量 A、B 和 D 密切相关,可以根据施加的雷击分量的幅度和上升率进行估计。雷击后损坏区域的增加是由闪电分量 C 由于其显着的热效应驱动的。根据电作用积分和转移电荷的参数对损坏区域进行评估。
