▎ 摘　　要

NOVELTY - The film comprises a graphene sheet (25) that is extended to surface direction. A resin sheet (26) is provided in out-plane direction orthogonal to the surface direction of the graphene sheet by laminating. The graphene sheet and the resin sheet are formed in a sheet form by making the surface direction or the out-plane direction into thickness direction while laminating in several numbers. The adhesive layer is provided between the graphene sheet and the resin sheet in out-plane direction. The thermally-conductive film is provided in one surface side on both sides of the composite material used as heating object. A heating unit is provided in other surface side on both sides of composite material, and is adapted to heat thermally-conductive film. USE - Thermally-conductive film of heating apparatus mounted in gas turbine engine (all claimed) of aircraft. ADVANTAGE - The ability to perform heat transfer having directivity is achieved. The ice coating in the nacelle of the gas turbine engine of the aircraft is prevented. Since the thermally-conductive film is positioned according to the aspect of a heating target object, the efficient performance of temperature rise by heating of the thermally-conductive film is achieved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a gas turbine engine. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a structure of a thermally-conductive film.
