    Abstract: The present application discloses a high-performance metal matrix composite (MMC) vehicle braking component, two methods of making a porous ceramic insert, a method of making an MMC comprising a porous ceramic insert, and a method of making an MMC not comprised of a porous ceramic insert. In one exemplary embodiment the porous ceramic insert is comprised of a ceramic compound and a sacrificial insert. In another exemplary embodiment the porous ceramic insert is comprised of one or more ceramic compounds and one or more ceramic preforms. The high performance MMC vehicle braking component has two distinct friction portions that extended from the outer surfaces to the thermal management portion of the high performance MMC vehicle braking component.

    Abstract: An exemplary method for making a metal matrix composite vented brake rotor includes: providing a first side plate; providing a second side plate; and welding the first and second side plates together. The first and second side plates have outer surfaces, inner surfaces, and metal matrix composite portions extending from the outer surfaces to a distance from the inner surface that is less than a thickness measured between the inner surface and outer surface. The inner surface of the first side plate includes a vent portion. The step of welding includes welding the first vent portion to the second inner surface to form the vented brake rotor, the vented brake rotor having a plurality of vents formed by the first and second inner surfaces and the first vent portion.
