Abstract
A layered construction is provided having a storage modulus G'at 25° C., comprising: a) a cured polymeric composite having a storage modulus G′at 25° C.; and b) a cured surfacing film bound thereto; wherein G′is not greatly elevated over G′, typically not more than 118% of G′. 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.
