Carbon composite material |
摘要 |
The present invention provides a carbon composite material which is a molded material comprising (a) an expanded graphite powder and (b) a thermoplastic resin or a thermosetting resin or a fired product of the thermosetting resin, and the expanded graphite powder (a) being dispersed in the component (b); wherein the expanded graphite powder has an average particle diameter of 5-12 mu m and at least 80% of the total particles of the expanded graphite powder have particle diameters of 0.1-20 mu m; and a process for producing a carbon composite material, which comprises mixing and dispersing a thermoplastic or thermosetting resin and the expanded graphite powder as mentioned above, and then pressure-molding the resulting mixture at room temperature to 400 DEG C., or a process for producing a carbon composite material, which comprises mixing and dispersing a thermosetting resin and the expanded graphite powder as mentioned above, pressure-molding the resulting mixture at room temperature to 400 DEG C., and firing the resulting molding at 700 DEG -3,000 DEG C. in a non-oxidizing atmosphere. The carbon composite material produced by the above process is free from the problems of the prior art and is superior in both gas non-permeability and electroconductivity.
