Tribology and Wear Analysis

In order to meet the requirements in thermal management, a novel kind of carbon/metal composites, namely graphite film/aluminum laminate composites with excellent thermal properties, was developed. The effects of oxide films on interfacial structure and properties of the composites were identified, and the microstructures and properties of the composites were studied as a function of the volume fraction of graphite films. An ultrahigh thermal conductivity of 902 W/mK for aluminum matrix composites was obtained. The measured in-plane thermal conductivities of the composites are all over 80% of the rule of mixtures prediction. What's more, these composites are shown to have more competitive thermal conductivities as compared to other kinds of carbon/aluminum composites, which makes these composites promising candidates to be used for thermal management.
