Abstract
Section titled āAbstractāHigh volume fraction diamond/copper composites with different diamond shape were prepared by vacuum pressure infiltration. In this paper, the effect of diamond type on thermo-physical properties of the composites was researched. The results showed that the composites with broken diamond exhibited the lowest thermal conductivity and coefficient of thermal expansion, only 401W/mā¢k and 6.2Ć10 -6 m/K respectively, and the composites with monocrystalline diamond had the best properties, reaching to 527W/mā¢K and 8.3Ć10 -6 m/K respectively, and the properties of the composites with modified-shape diamond were in the middle. The difference in the properties of the composites with different-shape diamond is attributed to their various specific surface areas.
