Reinforcement effects of MWCNT and VGCF in bulk composites and interlayer of CFRP laminates
(0) INTRODUCTION Multi-walled carbon nanotubes (MWCNTs) and vapor grown carbon nanofibers (VGCFs) are receiving steadily increasing attention because of their excellent mechanical properties. By employing them as fillers in polymer-based composites, it is expected that the overall mechanical properties of composites can be improved 1, 2. In this report, the reinforcement effects of MWCNT and VGCF, which are used as reinforcement fillers in the interlayer of conventional CFRP laminates, and in epoxy bulk composites, have been investigated. When using two fillers in the interface between two conventional CFRP laminae, it can be found that the Mode-I interlaminar tensile strength and fracture toughness of CFRP laminates are improved. The performance of VGCF is better than that of MWCNT in this case. For epoxy bulk composites, the tensile strength of epoxy/VGCF is higher than that of epoxy/MWCNT. However, the Mode-I fracture toughness of epoxy/MWCNT is much better than that of epoxy/VGCF.
