The adhesive bonding pretreatment is an important process in the bonding of aerospace composites. The bonding strength of the adhesive bonding interface will directly be affected by adhesive bonding surface properties after pretreatment. Based on the 50kHz infrared pulse laser processing of carbon fiber reinforced resin-based composites, the effects of laser power and scanning speed on the surface morphology of carbon fiber reinforced plastics are investigated by analyzing the laser cleaning microtopographies under different parameters. The results show that the laser output power is 25.9W and the scanning speed is 9000mm/s, with the surface resin completely removed and the carbon fibers not being burned.
