Effective Thermal Conductivity Model of High Volume SiC_p/Al Composite

The effective thermal conductivity is a very important property index of aluminum matrix composite for electronic packing and heat control applications.Based on the Maxwell theory and the generalized self-consistent scheme micromechanics models,the theoretical model for predicting the effective thermal conductivity of high volume fraction SiCp/Al composites is constructed,in which the interfacial effects between SiC particles and particles Al matrix are considered,and the shapes of particles are also considered in a degree.The calculations of the model are close to the experiment results.
