  • Fast process for the production of fiber preforms
    Patent number: 6129868
    Abstract: A thermomechanical pressing ("TMP") method for obtaining rapidly a high density (1.2 g/cm.sup.3 or higher) carbon/carbon composite preform from any carbon fiber including PAN-based carbon fibers and industrial coal-tar or petroleum pitches (including synthetic derivatives) having a melting point m.p.=80-350.degree. C. Green preforms may be prepared from mixtures of carbon fibers and pitch, and the resulting mixture is formed to impart a cylindrical shape to the green preform. The green preform is charged into a metallic mold where it is heated, stabilized, pressurized for a period of time, and cooled.
