Abstract: An aluminum/diamond composite for the manufacture of metal structures having high yield strength, high stiffness, high thermal conductivity, and low coefficient of thermal expansion. The composite consists of aluminum metal with included diamond particles. The volume fraction of diamond particles may range from 5% to 80%, but is most preferably about 30% to 40%. Two methods of manufacture of the composite are disclosed. The material may be used to manufacture gun barrels, rocket nozzles, cookware, heat sinks, electronics packaging, and automotive components such as brake disks, brake drums, transmission components, and engine components.

Abstract: Ceramic oxide pre-forms comprising substantially continuous, ceramic oxide fibers, and methods for making the same. The ceramic oxide pre-forms are useful, for example, as in making metal matrix composites reinforced with substantially continuous, ceramic oxide fibers.
