Carbon fiber reinforced polymer (CFRP) is one of the most important construction materials in civil aircraft manufacturing. In the current paper, effects of laser surface treatment on the surface microstructure of the CFRP are involved. And the influence of laser surface treatment parameters on shear strength and failure pattern are considered. The optimized parameters including laser scanning speed, laser power, frequency and power density are expected to ensure that the resin and all kinds of pollutants on the surface are cleaned. It is indicated that laser power density significantly influences the surface morphology. The surface with continuous and integrated fibers is helpful for adhesive bonding and is acquirable under appreciate parameters. Maximum shear strength (27 MPa) of adhesively bonded joint was obtained after laser surface treatment.
