Abstract
The disclosure provides a method for surface treatment of a composite material part and the prepared part. The method comprises the steps of: (1) providing a surface of a carbon fiber composite material part; (2) preparing a surface protection layer; (3) polishing the carbon fiber reinforced resin-based composite material surface after transparent powder is cured; (4) spraying transparent powder to the carbon fiber reinforced resin-based composite material surface after the transparent powder thereon is cured and curing it; (5) polishing the carbon fiber reinforced resin-based composite material surface after the transparent powder is cured; and (6) spraying a clear lacquer to the carbon fiber reinforced resin-based composite material surface after the transparent powder is cured and curing it.
