摘要： This invention relates to metal and ceramic matrix composite brake rotors comprising an interconnected matrix embedding at least one filler material. In the case of metal matrix composite materials, the at least one filler material comprises at least about 26 % by volume of the brake rotor for most applications, and at least about 20 % by volume for applications involving passenger cars and trucks. In a preferred embodiment of the present invention, the metal matrix composite brake rotor comprises an interconnected metal matrix containing at least about 28 % by volume of a particulate filler material and more preferably at least about 30 % by volume. Moreover, the composite rotors of the present invention exhibit a maximum operating temperature of at least about 900 °F (482 °C) and preferably at least 950 °F (510 °C) and even more preferably at least about 1000 °F (538 °C).
