Abstract: Metallization on the surface of carbon fiber composite reflector can effectively reduce the energy consumption of electromagnetic wave on the surface of reflector, while robot spraying can effectively solve the problem of unstable quality and low efficiency of artificial spraying products. Based on the spraying process of the robot, the influencing factors of the spraying process have been analyzed. The first is the trajectory of the robot, including the walking path pattern of the robot and the distance between adjacent gun paths. The second is the parameters of the gun unit, including the air pressure, the speed of the spraying wire, the walking speed of the gun and the relative height of the gun from the base surface. Based on a reflector, the appropriate parameters of automatic spraying have been determined, and a composite satellite antenna reflector containing metal coating has been prepared. The porosity detection result is 0.162 %, and the roughness result is Ra 1.417 μm, both of which are better than the conventional requirements, laying a foundation for the subsequent optimization.
