Document Type and Number:
WIPO Patent Application WO/2019/087846
Kind Code:
A1
Abstract:
The present invention provides, at a low cost, a long-life molded heat insulation material in which a surface layer is formed and which can prevent the deterioration of heat insulation performance due to gas. This molded heat insulation material with a surface layer includes: a carbon fiber-based molded heat insulation material; an expanded graphite sheet laminated on the carbon fiber-based molded heat insulation material; and a carbon fiber sheet protective layer laminated in contact with the expanded graphite sheet, wherein the carbon fiber sheet protective layer has: a carbon fiber non-woven fabric sheet in which carbon fibers are entangled; and a carbonaceous matrix covering the carbon fiber surface of the carbon fiber non-woven fabric sheet.
