Zusammenfassung:	To provide a method and coating for protecting a surface of a non-metallic composite component.SOLUTION: A method comprises applying a protective coating layer to an exposed surface of a non-metallic composite component, the protective coating layer comprising: (a) a multilayer having at least one co-cured layer applied to a surface of the non-metallic composite component and at least one laser-sensitive layer applied to a surface of the co-cured layer, where the laser-sensitive layer is selected from a reflective layer, an optical sensor layer, and a layer having both reflective and optical sensor properties; or (b) a co-cured coating which comprises a laser-sensitive material incorporated therein to form a laser-sensitive co-cured layer applied to the surface of the non-metallic composite component, where the laser-sensitive material is selected from a reflective material, an optical sensor material, and a combination thereof, such that the non-metallic composite component will be protected from damage during subsequent laser ablation to remove an outer coating.SELECTED DRAWING: Figure 2 【課題】非金属複合部品の表面を保護するための方法とコーティングを開示する。【解決手段】本方法は、非金属複合部品の露出表面に保護コーティング層を適用することを備え、保護コーティング層は、（ａ）非金属複合部品の表面に適用された少なくとも一つのコキュア層と、コキュア層の表面に適用された少なくとも一つのレーザー感応層とを有する多層を備え、レーザー感応層が、反射層と、光学センサ層と、反射性と光学センサ性の両方を有する層とから選択され、又は、（ｂ）非金属複合部品の表面に適用されたレーザー感応コキュア層を形成するように含有されているレーザー感応物質を備えるコキュア性コーティングを備え、レーザー感応物質が、反射物質と、光学センサ物質と、これらの組み合わせとから選択され、外面コーティングを除去するための後続のレーザーアブレーション中に非金属複合部品が損傷から保護されるようにする。【選択図】図２
