Abstract: Briefly, the present disclosure provides a film, tape or outer layer of a composite part comprising: a) at least one layer comprising a crosslinked polymer selected from the group consisting of crosslinked polyurethane, crosslinked polyurea, and crosslinked mixed polyurethane/polyurea polymer; and in some embodiments b) an adhesive layer. In some embodiments the layer additionally comprises a non-crosslinked polymer forming a semi-IPN with the crosslinked polymer. In some embodiments the non-crosslinked polymer may be selected from the group consisting of polyurethane, polyurea, and mixed polyurethane/polyurea polymer. In some embodiments the crosslinked polymer may additionally comprise an acrylate-containing component.
