摘要： The mesophase pitch based and melt blown discontinuous carbon fibers of a peculiar structure are provided. These fibers are characterized in that a large number of small domains, each domain has an average equivalent diameter of from 0.03 µ m to 1 µ m and has a nearly uniform orientation of carbon layers, assemble to form a mosaic structure on the cross-section of the said carbon fibers and that the orientation of the carbon layers is observed to be essentially random or radial on the whole of the cross-section of the said carbon fibers.

摘要： 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 of 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.

摘要： A process for producing a reformed pitch useful for various carbon materials is provided. This process comprises mixing a pitch having a ratio of aromatic hydrocarbon fa of 0.6 or more with a Lewis acid and a co-solvent so as to give a mol ratio of the said Lewis acid to the said pitch in the range of 0.3 ∼ 5.0 and a mol ratio of the said co-solvent to the said pitch in the range of ratio of 2.5 ∼ 50, reacting the mixture at a temperature of 100 ∼ 300°C and removing the Lewis acid and the co-solvent from the reaction product. Meso-Carbon microbeads having a uniform diameter of 20µm or less can be produced at a high yield of 60% or more by heat treating the reformed pitch at 200 ∼ 380°C to produce the optically anisotropic small spheres and separating them from an optically isotropic matrix.
