CFRP (Carbon fiber reinforced plastic) is attracting attention for weight reduction mainly in transportation equipment and thus the joining technique between CFRP and metals is strongly required. On the other hand, the bonding method between CFRP and metal has not been well optimized. The purpose of this research is to improve the adhesive strength by forming many holes on the CFRP surface before bonding. By using the anchor effect of holes, we aim to improve the adhesive strength. The results of adhesion experiments show that the strength is improved by the holes on the surface although, in some cases, the adhesive did not penetrate sufficiently and air bubbles remained in the holes.
