Abstract

In this study, we compared carbon fiber reinforced plastic (CFRP) and Namd^TM CFRP (CFRP which includes carbon nanotube (CNT), and it was developed by NITTA CORPORATION [1]). The commercial finite element analysis (FEA) software Abaqus was used for the analysis. In the analysis, we conducted collision simulation using conventional CFRP laminate and Namd^TM CFRP laminate model. We expressed the ply crack by Hashin damage theory and express the delamination by cohesive contact. In collision analysis, impactor collided with Namd^TM CFRP laminate and conventional CFRP laminate, and we compared the delamination and cracks in each layer of laminate. Comparing Namd^TM CFRP and conventional CFRP, the laminate of Namd^TM CFRP was less damaged than the laminate of conventional CFRP. The simulated results showed that impact damage resistance is improved by CNT.
