Damage analysis of carbon fiber composites exposed to combined lightning current components D and C

The damage properties of carbon fiber reinforced polymer (CFRP) laminates exposed to combined lightning components D and C were explored by standardized artificial lightning tests, and then evaluated by visual inspection and ultrasonic scan. To interpret the heating mechanism of CFRPs under the combined lightning components D and C, a mathematical model of lightning arc was involved in the finite element analysis, the results of which agreed well with experimental data. It was revealed that the component D controlled the in-plane damage area, while the sequential injection of component C aggravated the in-plane damage extent and tended to induce in-depth damage. The simulated results indicated that the resistive heating effect played a leading role in thermal damage of CFRPs during component D, whereas the damage occurred in component C was dominated by lightning arc heating effect.
