Fabrication and properties of graphite flakes/metal composites for thermal management applications


R. Prieto, J.M. Molina, J. Narciso, E. Louis


Carbon-based/metal composites are materials showing excellent thermal performance. Graphite flakes are attractive carbonbased reinforcements in terms of thermal properties, price and machinability. However, their packed preforms pose insurmountable difficulties to metal infiltration. Here a novel fabrication process is discussed which consists of using mixtures of graphite flakes and
other material with different morphology. Preforms of such mixtures can be easily infiltrated with a variety of metals and alloys. The thermal properties of the resulting composites are also reported.
