Abstract
A coated composite material comprising a composite substrate comprises a polymeric matrix with fibre reinforcement, a surface of the composite substrate being coated with a two-phase primer layer E and a coating layer A adhered to said outer surface of the two-phase primer layer E. The two-phase primer layer E comprises a reinforcing phase of material elements bound in a predefined distribution by a polymeric phase and at least partially exposed at an outer surface of the primer layer so as to provide a surface texture.

A coated composite material comprising:
- a composite substrate comprising a polymeric matrix with fibre reinforcement;
- a surface of the composite substrate being coated with:
- (i) a two-phase primer layer comprising a reinforcing phase of material elements bound in a predefined distribution by a polymeric phase and at least partially exposed at an outer surface of the primer layer so as to provide a surface texture;
- and
- (ii) a coating layer adhered to said outer surface of the two-phase primer layer.
A method of manufacturing a coated composite material, the method comprising:
- providing a composite substrate comprising a polymeric matrix with fibre reinforcement;
- coating a surface of the composite substrate with a two-phase primer layer comprising a reinforcing phase of material elements bound in a predefined distribution by a polymeric phase such that the reinforcing phase is at least partially exposed at an outer surface of the primer layer so as to provide a surface texture;
- and
- depositing a coating layer on said outer surface of the primer layer.
