| Summary: | The thermal-electric finite element simulation model of carbon fiber reinforced plastic(CFRP) damage caused by lightning strike was established. The superimposed temperature was treated as the internal injury. The accuracy and effectiveness of coupled thermal-electric simulation method were verified by comparing with the experimental results. The regression analysis was taken into consideration to give a quantitative analysis of lightning parameters and CFRP lightning damage, and the relevant curves were drawn. The results show that action integral is a key factor in determining the injury status of CFRP laminates. Fiber damage area and delamination area have a linear relationship with the action integral. And resin damage area and damage thickness have a logarithmic relation with the action integral. |
