Abstract: Carbon fiber composite material (CFRP) is widely used in the manufacture of aircraft structures and components in the aviation field. Because aircraft often works in some harsh conditions, the surface coating of carbon fiber will age and lose its original performance. The longer the aircraft is in service, the deeper the coating needs to be removed. The coating of CFRP was quantitatively peeled by CO2 laser instead of the traditional mechanical grinding. The experimental results show that the preset requirements of 5 μm, 10 μm and 20 μm removal can be achieved under the power of 20 W, 25 W and 30 W, within a certain error permissible range. In addition, the mechanical properties of the material are not weakened, which meet the requirements of recoating.
