The Effective Continuum Micromechanics Analysis Code was modified to predict the effective thermal conductivities of composites containing multiple distinct nanoheterogeneities (fibers, spheres, platelets, voids, etc.) each with an arbitrary number of coating layers based upon either the modified Mori-Tanaka or modified self-consistent methods for steady state heat conduction. A parametric study was performed to investigate the effect of nanoreinforcement morphology, volume fraction, orientation, and nanoreinforcement-resin interphase properties on calculated effective thermal conductivities. Predicted thermal conductivities matched experimentally measured values for vapor-grown carbon nanofiber/polypropylene, exfoliated graphite flake/epoxy, glass microsphere/polystyrene, cupric oxide sphere/epoxy, and aluminum sphere/epoxy composites. © 2013 Elsevier Ltd.
