Patent ID: 10442550

Abstract:
A layered construction is provided having a storage modulus G′t25 at 25° C., comprising: a) a cured polymeric composite having a storage modulus G′s25 at 25° C.; and b) a cured surfacing film bound thereto; wherein G′t25 is not greatly elevated over G′s25, typically not more than 118% of G′s25. In some embodiments the cured surfacing film comprises an electrically conductive layer, typically a metal layer. In some embodiments the cured surfacing film comprises a cured epoxy resin which may optionally be a chain-extended epoxy resin and may excludes phosphorus. The resulting layered construction may display high erosion resistance, high corrosion resistance, and high resistance to microcracking. In another aspect, methods of making the subject layered constructions are provided.
