Coatings On Fiber Reinforced Composites
Patent #: 6,982,116
Inventor(s): Richard Passman and David McPherson
Company: Praxair S.T. Technology, Inc
Patented is a fiber reinforced composite material comprising a fiber reinforced polymer substrate and a first polymeric layer coating for joining two different polymeric composites. The first polymeric layer is free of fibers and particulate. A second polymeric layer coats the first polymeric layer and comprises a polymeric matrix and a particulate within the polymeric matrix. The second polymeric layer contains about 20 to 85 weight percent particulate. The particulate in the second polymeric layer is a metal and at least one thermally sprayed material coats the second polymeric layer to form an adherent multilayer coating attached to the fiber reinforced polymer substrate. The multilayer coating is attached to the fiber reinforced polymer substrate with a tensile strength of at least about 10 MPa.
