The interfacial interaction between carbon fibre and epoxy matrix is critical to the mechanical performance of fibre-reinforced composites. In this research we graft vertical graphene (VG) on single carbon fibres using plasma-enhanced chemical vapour deposition (PECVD). The effects of VGs grafting on carbon fibre surface roughness, wettability, tensile strength, as well as the interfacial shear strength (IFSS) between carbon fibre and epoxy are investigated. Our results show that both the surface roughness and the wettability towards epoxy could be dramatically increased by grafting VGs on carbon fibre surface. Single fibre tensile tests also confirm that the grafting of VG on carbon fibres doesn't degrade the fibre in mechanical strength, while the IFSS of carbon fibre/epoxy composites is significantly improved. This research demonstrates the potential of grafting VGs on CF in improving the mechanical properties of carbon fibre reinforced composites, and also provides possibility to develop multifunctional hierarchical carbon fibre reinforced composites with better performance.
