Abstract
Both temperature dependent model and pyrolysis dependent model were proposed to investigate the lightning strike damage of carbon fiber reinforced polymer (CFRP) composite laminates, where lightning in-plane and in-depth damages were evaluated by the two models, respectively. Firstly, the simulated results were compared with the experimental data of IM600/133 composites to determine the feasibility of the models. The results affirmed that lightning in-plane damage evaluated by temperature dependent model had a good agreement with experimental results while the lightning in-depth damage evaluated by pyrolysis dependent model matched well with experimental results. Then the proposed models and methods were confirmed by the simulation of the lightning strike damage of TR50S15L/YPH-308 laminates and the comparison between the simulated and experimental results. The appropriate models and methods to evaluate lightning in-plane and in-depth damages are helpful for the research of lightning damage behaviors, mechanisms and anti-lightning optimizations of CFRP.
