1. A fiber reinforced composite material comprising: a fiber reinforced polymer substrate; a first polymeric layer coating the fiber reinforced polymer substrate for joining two different polymeric composites, the first polymeric layer being free of fibers and particulate; a second polymeric layer coating the first polymeric layer, the second polymeric layer comprising a polymeric matrix and a particulate within the polymeric matrix, wherein the second polymeric layer contains about 20 to 85 weight percent particulate and wherein the particulate in the second polymeric layer is a metal; and at least one thermally sprayed material coating the second polymeric layer to form an adherent multi-layer coating attached to the fiber reinforced polymer substrate, the multi-layer coating being attached to the fiber reinforced polymer substrate with a tensile strength of at least about 10 MPa. |
