PROBLEM TO BE SOLVED: To provide a method of manufacturing carbon fiber reinforcing carbon material which is needless of secondary compacting process, high in production efficiency, low in cost, high in density of elaborate texture, and high in strength. SOLUTION: The method of manufacturing carbon fiber reinforcing carbon material is characterized in that a prepreg obtained by impregnating thermosetting resin into the carbon fiber, hardening, and forming is heat treated in a non-oxidizing atmosphere at the temperature of 400-700 deg.C, the obtained primary baked matter is carbonized under the pressure of 4.9-29.4 MPa at the temperature of 1,000-2,300 deg.C. |
