Damage behavior of CFRP subjected to simulated lightning current under air, reduced-pressure air, and N2 environments

This study examined lightning strike damage behaviors of carbon fiber reinforced plastic (CFRP) laminates under air (0.1 MPa), reduced-pressure air (0.02 MPa), and N2 (0.1 MPa) environments to elucidate the effects of atmospheric environments on lightning damage. Simulated lightning current in accordance with SAE-ARP 5412B was applied to each specimen. The maximum current peak value was defined as 40 kA. CFRP laminates under reduced-pressure air...
