<p>A blanket (10) formed of heat and flame resistant materials and adapted to be placed adjacent to a structural part (24) to isolate it thermally from other, adjacent structural parts (22). The blanket (10) is comprised of a layer (12) of insulation material coupled to a layer (18) of fibrous material impregnated with a thermosetting resin. When the blanket (10) is in a desired shape, the resin is cured to render the layer (18) of fibrous material substantially rigid so it can support itself as well as the layer (12) of insulating material coupled to it. Layers (14) and (16) of glass fabric are placed on opposed sides of the layer (12) of insulating material to keep the insulating material intact. In one application, the blanket (10) is molded in the form of a box-like structure which can at least partially surround a structural part, such as an aircraft engine (24), to form a fireshield to isolate the engine (24) from adjacent structural partsof an aircraft. In another application, the resin-impregnated layer (18) of fibrous material of the blanket (10) 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 (18) of fibrous material is used without the layer (12) of insulating material and, when the resin is cured, the layer (18) is rigid and forms a box-like structure for at least a partially enclosing a structural part.</p> |
