Abstract: The present disclosure is directed to a composite structure comprising at least one reinforced polymer layer comprising a reinforcing material; a layer comprising a metal substrate comprising a surface and a conformal organic coating present on at least a portion of the surface; wherein the layer comprising the metal substrate is in direct contact with the reinforced polymer layer, and the reinforcing material is more noble than the metal substrate. Also disclosed is a method of making a composite structure, a surfacing film, and a test method for evaluating the galvanic corrosion resistance of a metal substrate test piece.
