    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.degree. 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.degree. C., and firing the resulting molding at 700-3,000.degree. 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.

    摘要： An improved method and apparatus for the production of a strand of reinforced graphite-foil yarn which is the basis of the braided graphite-foil yarns. To produce the reinforced graphite-foil strands what is needed is apparatus for a tapered, cone shaped circular die having a specific geometry suitable for curling the fiber and adhesive coated surface inward upon itself, so that the curled ribbon will adhere to itself when compressed into the final protrusion die forming a finished fiber reinforced composite strand of expanded graphite flake having suitable tensile strength, flexibility, and toughness to permit braiding, weaving and other processing making it commercially useful wherever a dry, lubricous, strong, flexible material is desirable.

    摘要： Finely-divided graphite flake is heated to a high temperature in the presence of boron or a boron-containing compound to cause the boron to permeate the crystal structure of the flake, which is then subjected to an intercalating agent and rapidly heated, resulting in an expanded or vermicular graphite with a bulk density substantially less than what might be expected if the flake were not pretreated with boron. The expanded graphite then is compressed to form a preform that is reduced in thickness by rolling or molding to form a higher-strength flexible graphite foil than heretofore.
