Experiment research of CFRP destroyed by lightning current

In order to study the direct effect of carbon fiber reinforcement plastic (CFRP) material by lightning current destroy, damage experiment and analysis have been investigated in this paper. CFRP laminate damage is tested under different artificial lightning waveform with same peak value and different peak value with same rise-time and half-width, respectively. The influence of lightning parameters to destroy area is analyzed and damage behavior is concluded. Damage area of CFRP laminates after artificial lightning destroy is detected by nondestructive ultrasonic C-scan testing. This research can provide some basic data for aircraft lightning protection designers.
