PURPOSE:To provide the method, by which a carbon-reinforced carbon composite material having mechanical characteristics and frictional coefficients used for various kinds of applications and satisfying requests can be obtained. CONSTITUTION:Short-fiber state carbon fiber bundle comprising a plurality of single fibers is decomposed. A sheet, wherein the fibers are oriented at random in two directions, is formed. After the bundle is impregnated with resin or pitch, the sheets are laminated and molded. Then, burning and densification are performed. Thus, the carbon-fiber reinforced carbon composite material is manufactured. At this time, the fiber decomposing degrees of the carbon fiber bundles in the inner part and the surface part of the composite material are made different. Thus, the desired frictional and mechanical characteristics are obtained. This is the method of manufacturing a carbon-fiber reinforced carbon composite material having these characteristics. |
