摘要: 为研究不同防护方式下的碳纤维复合材料层合板雷击损伤特性,对无防护、喷涂铝层防护、铜网防护的三种碳纤维复合材料层合板进行了雷击仿真与试验研究。在有限元仿真软件中建立三种层合板模型,统一施加A+B+C*组合波形雷电流,分析了不同防护方式下层合板的损伤特性,同时还对不同特征参数的铜网的防护效果进行了评估。仿真与试验结果表明:无防护层合板损伤与其铺层方向相关,喷涂铝层防护层合板损伤形状近似为圆形,铜网防护层合板损伤形状近似为椭圆;喷涂铝层与铜网均有效减小了层合板的损伤面积与损伤深度;铜网防护层合板损伤面积与损伤深度随铜网梗宽的增大而减小。

Abstract: In order to study the lightning damage characteristics of carbon fiber composite laminates under different protection methods, the lightning damage of three kinds of carbon fiber composite laminates, which are unprotected, aluminum-coated and copper-mesh-protected, is studied by the way of simulation and test. Three kinds of laminated plate models are established in the finite element simulation software, and A+B+C* combined waveform lightning current is uniformly applied to analyze the damage characteristics of the laminated plate under different protective methods, at the same time, the protective effect of copper mesh with different characteristic parameters is evaluated. The simulation results show that the damage shape is determined by the conductivity laminates. The damage shape of unprotected laminates is related to the laminates, the damage area and depth of the laminate are reduced effectively with protection of spraying aluminum or copper mesh, the damage area and damage depth decrease with the increase of the width of copper mesh. The validity of the finite element model is verified by experiments.

Key words: carbon fiber composites, protective methods, electrothermal coupling, damage area, depth of damage
