Interpenetrating phase composites (IPCs) are characterized by the presence of either of both phases in a bi-phase composite system forming a connected network throughout the sample. Such materials are of engineering interest as multi-functional materials can be designed for a specific application. In this study, we obtain scale-dependent bounds on the effective thermal conductivity of Gaussian correlated two-phase composites.
