Carbon Fiber Reinforced Polymer (CFRP) has been established as an excellent strengthening material. The performance of CFRP steel members is directly dependent on the quality of the adhesive bond. In this study, different blasting angles were compared, the surface properties and the adhesive strength of blast treated steel plates were discussed. The surface roughness, amount of residual Al at the steel surface, and adhesion strength according to the adhesion test were performed to determine the effect of blasting angles on the adhesive bonding behavior of CFRP/steel composite member.
