The attributes existing in a composite such as a different volume fraction, grain size, contiguity or porosity, etc. determine a thermal conductivity of composite. To achieve a good heat dispersal technique, this study obtained the information by simulation which is time and energy frugal. By using the Monte Carlo method to consider phase boundaries, one can derive the thermal conductivity of composite on various materials. The cited experimental curves agree analogously with simulation appearances found in this study. Both this work and some literatures point to the volume fraction or grain sizes and porosity as major factors in different results of thermal conductivity.
