Abstract

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 <=20mum, especially <=15mum. The lengths of both fibers are preferable to be 10-100mm, especially 20-50mm, for increasing a dispersion efficiency in an opening, and also keeping a bending strength of a compact. The above- mentioned mixture is settled, sedimented, and the obtained mixed fiber deposit is heated at 150-180 deg.C. Said compact is then calcined by heating at >=800 deg.C, and the porous carbon material is produced thereby.
