Flame barrier insulating laminate and flame barrier insulating structure using the same

Abstract

The present invention provides a sheet-like thermal insulating material (flame barrier insulating laminate) that is shapable into a three-dimensional and has excellent handling properties, and a thermal insulating structure with a three-dimensional shape made from the laminate. The flame barrier insulating laminate comprises at least one flame barrier insulating layer and one prepreg layer. The flame barrier insulating layer is made of a sheet having a thickness of 0.1 to 3.0 mm, in which inorganic fibers with a heat resistance temperature of 1000° C. or higher are entangled in a random direction. The prepreg layer is a prepreg sheet in which an inorganic fiber base fabric is impregnated with a semi-cured thermosetting resin. The thermosetting resin of the prepreg layer in the flame barrier insulating laminate is fully cured, resulting in a flame barrier insulating structure with a desired shape.
