    Abstract

    A fabrication of a carbon-carbon (C/C) composite, in which fine pulverized coke is used as carbon material of matrix, was carried out using three types of carbon fibers, that is, short fibers, long fibers, and cloth. The bending strength of the composite is highest with long fibers 3 to 5 times as high as of ordinary carbon material, then cloth and short fibers. A still stronger C/C composite could be obtainable with long fibers by improving dispersion of these fibers in the matrix. Accordingly, the C/C composite obtained through this study imply a success in development of such composite materials by means of a simple process.
