Abstract
A process for producing a high density, high strength carbon-carbon composite which does not require high cost secondary reinforcement treatment. This process comprises impregnating an aggregate such as a bundle of a carbon fiber with a liquid dispersion of a carbonaceous material of specified size of a fine powder or a short fiber of carbonaceous material to form a reinforcement material of a carbon fiber having the fine powder or the short fiber of a carbonaceous material distributed on the surface as well as in the inside of said bundle of a carbon fiber, and impregnating said aggregate of a carbon fiber with one or more liquid carbonaceous material selected from the group consisting of a phenolic resin, a furan resin and a pitch and carbonizing the impregnated bundle of a carbon fiber, and if necessary, graphitizing the carbonized product.
