Erosion resistant films for use on heated aerodynamic surfaces

摘要

An erosion resistant construction comprising: a) an element of an aircraft comprising: i) an aircraft skin segment having an external surface, and ii) a defrosting mechanism associated with said aircraft skin segment capable of heating said external surface at temperatures above 65 ° C; b) a belt comprising: i) at least one layer comprising a semi-interpenetrating polymer network comprising a crosslinked acrylic polymer and a non-crosslinked polymer, selected from the group consisting of polyurethane, polyurea and mixed polyurethane / polyurea polymer and ii) an adhesive layer; wherein the tape is attached to the outer surface of the aircraft skin segment by means of the adhesive layer.
