Analysis of lightning ablation damage performance of glass fiber reinforced polymer materials

Abstract Glass fiber-reinforced polymer materials have been effectively used in civil aviation aircraft, but due to low electrical conductivity, a large area of ablation damage will occur after lightning strikes, which greatly threatens the safety aircrafts. Based on this, coupled electrical-thermal finite element analysis model for glass fiber reinforced is established, and results are compared with experiment, error rate 1.26%, verifies accuracy model. In addition, different influencing factors analyzed study protection characteristics carbon laminates. The show that resistance, they can reduce laminates under joint them aluminum coating. However, protective effects forms Among them, thickness coating has higher impact efficiency full spraying laminates, local
