Abstract

Disclosed are methods and coatings for protecting the surface of a non-metallic composite part (200), comprising applying a protective layer (300) to an exposed surface of the non-metallic composite part (200), the protective layer comprising: (a) a multilayer (310) having at least a co-cured layer (312) applied to the surface of the non-metallic part (200) and laser-sensitive layer (311) applied to a surface of the co-cured layer (312), wherein the laser-sensitive layer (311) is selected from a reflective layer, an optical sensor layer or a layer having both reflective and optical sensor properties; or (b) a co-cured coating which comprises a laser-sensitive material (320a) incorporated therein to form a laser-sensitive co-cured layer (320) applied to a surface of the non-metallic composite part (200), wherein the laser-sensitive material (320a) is selected from a reflective material, an optical sensor material or a combination thereof, such that the non-metallic composite part (200) will be protected from damage during subsequent laser ablation to remove an outer coating (500).
