METHOD FOR APPLYING A COATING WITH ENHANCED ADHESION TO A COMPOSITE MATERIAL SUBSTRATE, AND COMPOSITE MATERIAL SUBSTRATE OR AIRCRAFT COMPRISING SUCH COATING

摘要

A method for applying a coating to at least one face of a substrate made of thermoplastic composite material, wherein the method includes a step of applying an adhesive polydopamine layer to the face of the substrate before applying the coating to enhance the adhesion of the coating to the substrate. A thermoplastic composite material substrate thus coated is provided. A method for applying a coating to a composite material panel forming part of the outer skin of an aircraft is provided, wherein a zinc or graphene particle-filled adhesive polydopamine layer is applied to the panel before the coating is applied to enhance the adhesion thereof to the panel. An aircraft comprising a panel thus coated is provided.
