Abstract
The disclosure provides a method for treating a surface of a carbon fiber composite material, comprising the steps of: (1) pretreating a carbon fiber reinforced resin-based composite material; (2) spraying transparent powder to the surface of the carbon fiber reinforced resin-based composite material and curing it; (3) polishing the surface of the carbon fiber reinforced resin-based composite material after the transparent powder is cured; (4) spraying transparent powder to the surface of the carbon fiber reinforced resin-based composite material after the transparent powder thereon is cured and curing it; (5) polishing, cleaning and baking; and (6) spraying a clear lacquer to the surface of the carbon fiber reinforced resin-based composite material after the transparent powder is cured and curing it.
