Claim 0:
1. A laminated hybrid metallized polymer film for erosion protection of an aerospace composite structure, the laminated hybrid metallized polymer film comprising:
a metal foil layer being a topmost layer of the laminated hybrid metallized polymer film, the metal foil layer comprising one of, a titanium foil layer, a titanium alloy foil layer, a nickel foil layer, a nickel alloy foil layer, a stainless steel foil layer, or a stainless steel alloy foil layer, and the metal foil layer having a configuration comprising one of, a slotted metal foil, a perforated metal foil, an expanded metal foil, or a mesh metal foil;
a laminating adhesive layer directly underlying the metal foil layer, the laminating adhesive layer comprising one of, a urethane adhesive layer including a polyurethane adhesive layer, an epoxy adhesive layer, a polysiloxane adhesive layer, a silicone adhesive layer, or an acrylic adhesive layer, wherein the laminating adhesive layer has a thickness in a range of from 0.0001 inch to 0.0020 inch;
a polymer film layer directly underlying the laminating adhesive layer, the polymer film layer laminated to the metal foil layer with the laminating adhesive layer directly coupled between the metal foil layer and the polymer film layer; and
an adhesive layer directly underlying the polymer film layer, the adhesive layer directly adhering the polymer film layer to a substrate surface having one or more cut edges of the aerospace composite structure, wherein the adhesive layer has a thickness in a range of from 0.005 inch to 0.010 inch, and further wherein the adhesive layer and the laminating adhesive layer have a total thickness in a range of from 0.0051 inch to 0.012 inch,
wherein the metal foil layer, the laminating adhesive layer, the polymer film layer, and the adhesive layer form the laminated hybrid metallized polymer film, in a flexible form having improved handleability and installation, the installation of the laminated hybrid metallized polymer film being facilitated by a formability of the laminated hybrid metallized polymer film, the flexible form comprising one of, a tape, an applique, a sheet, or an overlay, for direct application over and to the substrate surface having the one or more cut edges of the aerospace composite structure, the aerospace composite structure comprising one of, a wing panel, a barrel section of a fuselage, a passenger door, an access door, a window surround, a horizontal stabilizer, or a vertical stabilizer, and the laminated hybrid metallized polymer film providing erosion protection of the aerospace composite structure from one or more erosion conditions, and preventing or minimizing delamination of the one or more cut edges of the aerospace composite structure.
