(c) Calculated thermal conductivity according to Agari’s model (C1 = 1, C2 = 1) and measured values at 298 K. (d) Thermal conductivities from vertical and parallel curing directions of the composites at 298 K. (e) Experimental thermal conductivity and f itted line as a function of Vf (volume fraction of fillers). (f) Thermal conductivity from fitted results.
