Abstract—By means of a generalized effective-field approximation, formulas are derived for the effective thermal conductivity of a three-component tribocomposite based on a phenylone matrix with spherical strengthening inclusions (alumoborosilicate glass) and inhomogeneous antifrictional inclusions (spherical capsules of glycerin in a Kapton® shell). The thermal conductivity is investigated as a function of the concentrations of inclusions and the ratio of the internal and external radii of the antifrictional inclusions.
