Inventors:

Thomas Charles Gray - Coral Springs FL, US

International Classification:

B31F 1/07

US Classification:

101 23, 101 28, 101 32

Abstract:

An apparatus for embossing a substrate is provided. The apparatus includes a die with a metal backing layer that carries a polymer layer. The polymer layer has a female pattern formed through laser engraving. The metal backing layer of the die is capable of being magnetically attached to a magnetic cylinder. A counter die is also included and has a metal backing layer that carries a polymer layer. The polymer layer has a male pattern formed thereon through laser engraving. The metal backing layer of the counter die is capable of being magnetically attached to a magnetic cylinder. An alternative apparatus is provided that includes a male and female starting member to aid in aligning the patterns. Another apparatus is included that has male and female register tracts for keeping the die and counter die in register with one another. An associated method is also provided.

US Classification:

192107M

Abstract:

This invention relates to metal and metal matrix composite materials that are useful as, for example, brake rotors, clutch plates and other similar uses which benefit from material properties of the invention. In the case of metal matrix composite materials, clutch plates and brake rotors made according to the invention comprise an interconnected matrix metal embedding at least one filler material. For example, the at least one filler material comprises numerous acceptable filler materials present in a sufficient quantity to provide desired performance. The brake rotors and clutch plates according to the invention further comprise a coating on the surface thereof causing the metal or metal matrix composite body to function as a substrate. The coatings may be applied by various conventional techniques. Desirable results of placing a coating on a metal or metal matrix composite substrate brake rotor or clutch plate include a significant increase in the maximum operating temperature of the brake rotor or clutch plate and/or a significant reduction in weight in comparison to conventional materials, etc.
