Impact and after-impact properties of nanocarbon aerogels reinforced epoxy/carbon fiber composite laminates

The experimental results showed that the impact resistance properties of the CFRP laminates steadily improved with NCAs at the addition of 0.3 wt%. In addition, the damage to the NCAs/CFRP laminates at the low impact energy of 20 J was observed by nondestructive evaluation, including ultrasonic inspection (C-scan) and thermographic analysis, to understand the delamination behavior of the NCAs/CFRP laminate.
