通过有限元模拟构建了电改性夹层碳纤维增强复合材料（CFRP）层合板雷击损伤数值模型，采用电-热-热解耦合分析方法同时考虑层内和层间雷击损伤。然后研究了雷击损伤程度，包括损伤体积和最大损伤深度。结果表明，模拟的雷击损伤可以与夹层镀镍多壁碳纳米管（Ni-MWCNT）改性的CFRP层压板的实验对应物进行定性比较。改性中间层的电导率越高，改性中间层的数量越多，损伤体积和最大损伤深度都减小。该工作为CFRP层合板的抗雷优化提供了有效的指导。
The numerical model of carbon fiber reinforced polymer (CFRP) laminates with electrically modified interlayers subjected to lightning strike is constructed through finite element simulation, in which both intra-laminar and inter-laminar lightning damages are considered by means of coupled electrical-thermal-pyrolytic analysis method. Then the lightning damage extents including the damage volume and maximum damage depth are investigated. The results reveal that the simulated lightning damages could be qualitatively compared to the experimental counterparts of CFRP laminates with interlayers modified by nickel-coated multi-walled carbon nanotubes (Ni-MWCNTs). With higher electrical conductivity of modified interlayer and more amount of modified interlayers, both damage volume and maximum damage depth are reduced. This work provides an effective guidance to the anti-lightning optimization of CFRP laminates.
