ABSTRACT:
A blanket formed of heat and flame resistant materials and adapted to be placed adjacent to a structural part to isolate it thermally from other, adjacent structural parts. The blanket is comprised of a layer of insulation material coupled to a layer of fibrous material impregnated with a thermosetting resin. When the blanket is in a desired shape, the resin is cured to render the layer of fibrous material substantially rigid so it can support itself as well as the layer of insulating material coupled to it. Layers of a heat and fire resistant fabric such as glass fabric are placed on opposed sides of the layer of insulating material to keep the insulating material intact. In one application, the blanket is molded in the form of a box-like structure which can at least partially surround a structural part, such as an aircraft engine, to form a fireshield to isolate the engine from adjacent structural parts of an aircraft. In another application, the resin-impregnated layer of fibrous material of the blanket is placed adjacent to one surface of a structural part and bonded thereto during the curing of the resin to thereby form a fireshield attached to the structural part. In a third application, the resin-impregnated layer of fibrous material is used without the layer of insulating material and, when the resin is cured, the layer is rigid and forms a box-like structure for at least partially enclosing a structural part.
