A braking component such as a brake pad, brake rotor, brake drum or clutch disk is comprised of a metal substrate having a friction material laminated on at least a portion of at least one face of the metal substrate, the friction material being a ceramic-metal composite comprised of a metal phase and a ceramic phase dispersed within each other, wherein the ceramic phase is present in an amount of at least about 20% by volume of the ceramic-metal composite. In particular, the braking component is a metal substrate, such as aluminum, having laminated thereto a ceramic-metal composite of a dense boron carbide-aluminum composite having high specific heat and low density.

[ What is claimed is:] [1.] A braking component for providing a frictional force comprised of a metal substrate having a friction material laminated onto at least a portion of a face of the metal substrate, the friction material being a ceramic-metal composite comprised of a metal phase and a ceramic phase dispersed within each other, wherein (i) the ceramic phase of the composite is comprised of at least one new ceramic that is a reaction product of the metal phase and a starting ceramic and (ii) the ceramic phase is present in an amount of at least about 20% by volume of the ceramic-metal composite.
