Beschreibung
Zusammenfassung:	PURPOSE:To produce a porous carbon material of superior heat insulation especially in high temp. range, with a simple method, by mixing a carbon fiber and unhardened phenol resin uniformly with a prescribed weight ratio, settling, sedimenting, and then molding said deposit of mixed fibers under heating, and calciming a molded body in a non-oxidizing atmosphere. CONSTITUTION:A carbon fiber and unhardened phenol resin are uniformly mixed in weight ratio of 1:4-4:1 by a dry process using an existing air dispersion apparatus, etc. The diameters of the above-mentioned both fibers are preferable to be
