Title:
COMPOSITE HEAT INSULATING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2011/058916
Kind Code:
A1
Abstract:
Provided is a composite heat insulating material which is inexpensively producible, is easily incorporated into an assembly, and, moreover, has thermal conductivity lower than 1.0 (W/m·K). The composite heat insulating material comprises: a rectangular tube-shaped honeycomb structure (16) having numerous housing spaces (14) which are divided from one another by thin walls (12); and ceramic powder (18) with which the insides of the respective housing spaces (14) of the honeycomb structure (16) are filled up. While the side faces of the honeycomb structure (16) are covered with outer walls (20) (for example, walls made of a material similar to that of the thin walls (12)), the upper and lower faces thereof are covered with plugging layers (22). A cross-sectional shape of the honeycomb structure (16) taken along a direction perpendicular to the axis thereof is a shape having the multiple thin walls (12) arranged in parallel with one another.
