Different bonding of carbon fiber reinforced plastic (CFRP) and metal attracts tremendous interest due to the increasing use of CFRP in the aerospace and automobile industries. In this study, in the direct laser bonding of the thermosetting CFRP and titanium plate, laser ablation was applied to the titanium plate as a pretreatment to improve the joint strength. In the laser ablation, the scanning speed and scanning direction were changed, and the effect of each on the joint strength was investigated. When laser ablation was performed under the condition of scanning speed of 100 mm/s in the direction perpendicular to the tensile direction during the tensile shear test, the joint strength was more than twice that of the untreated condition. However, when the scanning direction was laser ablated in the direction parallel to the tensile direction during the tensile shear test, the joint strength was about the same as the untreated condition.
