Abstract
The thermal conductivity of diamond hybrid SiC/Cu, diamond/Cu and SiC/Cu composite were calculated by using the extended differential effective medium (DEM) theoretical model in this paper. The effects of the particle volume fraction, the particle size and the volume ratio of the diamond particles to the total particles on the thermal conductivity of the composite were studied. The DEM theoretical calculation results show that, for the diamond hybrid SiC/Cu composite, when the particle volume fraction is above 46% and the volume ratio of the diamond particles to the SiC particles is above 13:12, the thermal conductivity of the composite can reach 500 W·m−1·K−1. The thermal conductivity of the composite has little change when the particle size is above 200 μm. The experimental results show that Ti can improve the wettability of the SiC and Cu. The thermal conductivity of the diamond hybrid SiCTi/Cu is almost two times better than that of the diamond hybrid SiC/Cu. It is feasible to predict the thermal conductivity of the composite by DEM theoretical model.
