초록

By bonding a graphite sheet possessing tightness to at least one surface of carbon fiber felt sheet possessing gas permeability by means of a carbonaceous binder, a multilayer thermally insulating material suitable for use in a heating furnace employing a nonoxidizing atmosphere is obtained. This insulating material has mechanical strength which does not decrease with a long period of use and gives rise to little contamination of articles being heated in the furnace.

청구항

A multilayer heat insulating material suitable for use in heating furnaces in which a non-oxidizing atmosphere is used, which insulating material comprises a sheet of carbon fiber felt having gas permeability, and a sheet of graphite having a thickness less than 1 mm. and a density of 0.6 to 1.6 grams/cm3, bonded to at least one surface of the sheet of carbon fiber felt by means of a carbonaceous binder, the density of said graphite sheet being substantially greater than that of said felt sheet.
