Abstract

1354875 Laminated products DEFENCE SECRETARY OF STATE FOR 13 May 1971 [15 May 1970] 23665/70 Heading B5N [Also in Division B7] A construction providing a surface having low adhesion for ice and forming at least part of an aerofoil surface of an aircraft or a rotor blade of a helicopter includes an outer skin of flexible organic polymeric material, which forms the surface of the construction, overlying the base structure of the aerofoil surface or rotor blade and a substrate of flexible sponge-like material interposed between the outer skin and the base structure so that the former is capable of flexing with reference to the latter. The outer skin is of polyethylene, polyurethane, PTFE, PVC or fluorinated ethylenepropylene copolymer and when of polyethylene, may be roughened and treated with chlorosulphonic acid. The flexible substrate is of polyurethane foam or sponge natural rubber and may be integrally skinned to provide the outer skin. Alternatively, the skin is attached to the substrate, and the substrate to the base structure, either around its edges, at intervals, or over its entire surface by means of an epoxy, cured neoprene or butadieneacrylonitrile-neoprene adhesive. In an example, the base structure is in the form of an aluminium plate.
