ABSTRACT:
An apparatus for making carbon discs for brake disc assemblies by feeding continuous strands of fibrous carbon material from spools into a die, the volume of the carbon material so dispensed being continuously monitored. A cutter terminates the dispensing operation and a debulking plate urges all of the fibrous carbon material so dispensed into the die alone. The material is compressed within a cylindrical annular die and, in one embodiment, is submitted to a convection curing oven where the preform is cured. Subsequently, the preform is carbonized, densified, and machined to form a final carbon disc brake. In another emobodiment, a dry preform is fabricated, obviating the need for curing and carbonizing.
