Heat insulating blanket

A heat insulating blanket comprising:

• a layer of fibrous material having a curable thermosetting resin impregnated therein and capable of withstanding temperatures up to a predetermined value;
• a layer of high temperature thermal insulating material, there being a pair of opposed layers of heat and fire resistant fabric on opposite sides of the layer of insulating material, one of the fabric layers being coupled to the layer of fibrous material;
• and a thread stitched through said fibrous material layer, the insulating material layer, and the fabric layer for coupling the layers together to form a composite insulating blanket adapted to be placed adjacent to a structural part to be protected.

A fireshield comprising a layer of high temperature thermal insulating material coupled to at least one layer of a woven ceramic cloth made from continuous ceramic fiber, said cloth layer having a curable thermosetting resin impregnated therein and capable of withstanding temperatures up to a predetermined value, said resin adapted to be cured to cause said layer to become rigid and to be self-supporting.

A method of making a fireshield for separating a pair of adjacent structural parts comprising:

• providing a heat insulating blanket formed from a layer of woven fibrous material impregnated with a curable thermosetting resin and separated from and coupled to a layer of high temperature thermal insulating material by a heat and fire resistant layer of fabric material;
• arranging the heat insulating blanket in a predetermined shape;
• and curing the resin when the same has said shape to cause the layer of fibrous material to become relatively rigid and to support the insulating material.

A method of making a fireshield for separating a pair of adjacent structural parts of adjacent structural parts comprising:

• providing a heat insulating blanket formed from a layer of fibrous material impregnated with a curable thermosetting resin and coupled to a layer of high temperature thermal insulating material;
• placing the heat insulating blanket in a predetermined shape adjacent to a structural part with said layer of fibrous material in engagement with one surface of the structural part;
• and curing the resin when the same has said shape to cause the layer of fibrous material to become relatively rigid and to support the insulating material, said curing step being performed when said layer of fibrous material is in engagement with said surface, whereby the layer of fibrous material is bonded to said structural part when the resin is cured.

A method of making a fireshield for separating a pair of adjacent structural parts of adjacent structural parts comprising:

• providing a heat insulating blanket formed from a layer of fibrous material impregnated with a curable thermosetting resin and coupled to a layer of high temperature thermal insulating material, said providing step including stitching the layer of fibrous material to said layer of insulating material;
• arranging the heat insulating blanket in a predetermined shape adjacent to a structural part with said layer of fibrous material in engagement with one surface of the structural part;
• and curing the resin when the same has said shape to cause the layer of fibrous material to become relatively rigid and to support the insulating material.

A method of making a fireshield for separating a pair of adjacent structural parts of adjacent structural parts comprising:

• providing a heat insulating blanket formed from a layer of fibrous material impregnated with a curable thermosetting resin and coupled to a layer of high temperature thermal insulating material, said providing step including placing a layer of heat and fire resistant fabric between the layer of fibrous material and the layer of insulating material, and stitching said layers together to form said heat insulating blanket;
• arranging the heat insulating blanket in a predetermined shape;
• and curing the resin when the same has said shape to cause the layer of fibrous material to become relatively rigid and to support the insulating material.

A method of making a fireshield for separating a pair of adjacent structural parts comprising:

• providing a layer of high temperature thermal insulating material coupled to layer of woven ceramic cloth made from continuous ceramic fiber impregnated with a curable thermosetting resin;
• forming the layers into a predetermined shape;
• and curing the resin to cause the impregnated layer to become rigid and self-supporting.
