Abstract
An aluminum matrix composite is provided comprising a preform formed from interwoven mats of graphitized vapor grown carbon fibers. The mats comprise semi-aligned, semi-continuous vapor grown carbon fibers which have been interwoven in situ during growth. The preferred method of producing the composite includes the steps of providing a vapor grown carbon preform and infiltrating molten aluminum into the interstices of the preform by a pressure casting process. The resulting aluminum matrix composite has a thermal conductivity of between about 600 W/m-K and 700 W/m-K and is useful as a component in electronic devices, aircraft, spacecraft, and other thermal management applications.
