Abstract
An aircraft insulation product comprising a glass fiber blanket faced on at least one major face with an air permeable sheet. Insulating fibers coated with unbonded binder are directed to a web of the permeable sheet material supported on a moving collection chain, and the resulting fibrous layer and the web are sent to an oven where the binder is cured. The collection web thus becomes bonded to the blanket by the binder to become an integral part of the insulation product. A plurality of stacked blankets, the edges of which are covered by a film, may be used instead of a single faced blanket.
Claims14
An insulation product especially suited for use as aircraft insulation, comprising:
- a fibrous insulation blanket containing fibers bonded together by cured thermosetting binder;
- the density of the blanket being in the range of 0.2 pounds per cubic foot to 1.5 pounds per cubic foot, and the thickness of the blanket being in the range of 3/8 inch to 2 inches;
- and
- a facing sheet bonded to a major face of the blanket by the cured thermosetting binder;
- the bonded facing sheet being permeable to air.
An insulation product especially suited for use as aircraft insulation, comprising:
- a plurality of fibrous insulation blankets aligned with each other in stacked face-to-face relationship, the blankets containing fibers bonded together by cured thermosetting binder;
- the density of the blankets being in the range of 0.2 pounds per cubic foot to 1.5 pounds per cubic foot, and the thickness of the blankets being in the range of 3/8 inch to 2 inches;
- at least an end blanket having a facing sheet bonded to the outer major face thereof by the cured thermosetting binder, the bonded facing sheet being permeable to air;
- and
- means covering the edges of the stacked blankets, said means being adhered to the outer facing sheet on said end blanket.
In an insulated aircraft fuselage, the improvement comprising:
- a fibrous insulation blanket containing fibers bonded together by cured thermosetting binder;
- the density of the blanket being in the range of 0.2 pounds per cubic foot to 1.5 pounds per cubic foot, and the thickness of the blanket being in the range of 3/8 inch to 2 inches;
- a facing sheet bonded to a major face of the blanket by the cured thermosetting binder;
- the bonded facing sheet being permeable to air;
- and
- the blanket being attached to the fuselage so that the facing sheet faces away from the fuselage toward the interior of the aircraft.
