Equivalent Inclusion Approach and Approximations for Thermal Conductivity of Composites with Fibrous Fillers

摘要

Based on the polarization approximations, the expression for the thermal conductivity of composites with randomly oriented inclusions of fiber forms is firstly derived. Equivalent inclusion approach is then developed to account for possible diversions such as non-idealistic geometric forms of the inhomogeneities, or the fact that the conductivity of the fibers is unknown, using reference conductivity data. Applications involving experimental data from the literature show the usefulness of the approach.
