ABSTRACT:
The disclosed carbon fiber felting material has a bulk density of 0.01 to 0.5 g/cm.sup.3 and a thermal conductivity of at most 1.0 kcal/m.multidot.hr.multidot..degree.C. in the thickness-wise direction thereof at 2,200.degree. C. The carbon fiber felting material is formed through physical and/or chemical interfiber entanglement. The carbon fiber felting material is very stable in an inert atmosphere, and excellent in heat insulating properties in a high-temperature range and against radiant heat transfer in particular.
