Abstract:
1. A fiber reinforced resin matrix composite part comprising a resin matrix and an outermost surface layer differing in composition from the resin matrix, wherein the resin matrix is an organic thermosetting or thermoplastic material, wherein the outermost surface layer is in the form of an adhesive tape comprising a layer comprising crosslinked polymer selected from the group consisting of crosslinked polyurethane, crosslinked polyurea, and crosslinked mixed polyurethane/polyurea polymer, wherein the layer further comprises a non-crosslinked polymer that has formed a semi-interpenetrating polymer network (semi-IPN) with the crosslinked polymer, and an adhesive layer, wherein the adhesive layer is disposed between the resin matrix and the layer comprising crosslinked polymer.
