Patent 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.

General Patent Information

Patent Description

This invention relates to a heat insulating unit for protecting structural components of different types of equipment from heat damage and, more particularly, to an improved heat insulating blanket capable of withstanding flame temperatures exceeding 2,000.degree. F.

The heat insulating blanket of the present invention, in a preferred embodiment, is formed from a composite structure including a layer of a fibrous material impregnated with a thermosetting resin and secured to a layer of insulating material by suitable attachment means, such as a thread which stitches the two layers together. The insulating layer may be in the form of a mat or particles, strands or fibers confined between a pair of heat and fire resistant layers, and the stitching will pass through all of the layers of the assembly.
