COMPOSITE CARBONACEOUS HEAT INSULATOR |
摘要 |
A composite carbonaceous heat insulator which comprises a carbonaceous heat-insulating member having a bulk density of 0.1 to 0.4 g/cm<3>, a carbonaceous protecting layer having a bulk density of 0.3 to 2.0 g/cm<3> and comprising a carbon fiber structure and a thermally decomposed carbon penetrated into the structure, and a thermally decomposed carbon coating layer having a bulk density higher than that of the carbonaceous protecting layer, wherein the above carbonaceous protecting layer is jointed to at least a part of the carbonaceous heat-insulating member to form a jointed body, and the thermally decomposed carbon coating layer is formed at least on the face of carbonaceous heat-insulating member in the surface of the jointed body; and a method for manufacturing the insulator. The heat insulator is reduced with respect to the depletion, deterioration and pulverization during the use thereof, while maintaining excellent insulating characteristics. |
