CFRP has been applied in various fields where it is mostly used as laminates. CFRP laminates are likely to fracture between the interlaminar surfaces. To resolve this problem, we proposed a self-healing system for CFRP using optical fibers and UV-curable resin. In this study, self-healing CFRP samples were prepared and the effectiveness of repairing the inter-laminar fractures was confirmed by using optical libers and UV-curable resin. In addition, we have also clarified the factors that affect the repair rate by determining the bonding strength of epoxy resin and UV-curable resin. From the experiment results, we were able to confirm the feasibility of the proposed self-healing system.
