Abstract: Systems, devices, and methods are provided for manufacturing a carbon ceramic brake disc. Generally, a plurality of uncured or partially-cured bulk molding compound preforms or molding compound layers and ventilation cores are placed in a mold cavity and warm-pressed at a first temperature. The ventilation cores are removed from the resulting cured green body. The cured green body is then removed from the mold, and treated through a polymer infiltration and pyrolysis or reactive melt infiltration process. Certain steps can be repeated until a desired target density or weight is attained.

Abstract: A friction damping cast component and method of production are disclosed. The components may be rotary, such as a cast brake rotor, or may be non-rotary, such as a cast suspension part or a cast engine block. Regardless of the type of component, a two-part vibration-damping insert having a thin metal core and a thin metal sheath is provided. The sheath fully encompasses the core in such a way that a dry sliding friction contact develops at their interfaces. The outer surface of the sheath with the metal core inside is rigidly bonded to the cast material that surrounds it during the casting process. The sheath surfaces may have a number of openings that allow a limited infiltration of molten cast iron material just inside the immediate vicinity of the sheath openings for spot rigid bonding between the surrounding cast material and the insert surfaces during casting.
