Abstract: The coefficients of thermal conductivity and heat capacity of carbon-filled plastic materials were determined by the dynamic calorimeter method on standard thermophysical devices over the range of temperatures $298\,\mathrm{To}\le T\le373\,\mathrm{To}$. As a result of the solution of the coefficient inverse problems, anisotropy is shown to have a weak effect on the restored effective coefficients of thermal conductivity, and the coefficients are determined as functions of temperature over the range to 1700 To are at a heating of samples by a plasma jet.

Keywords: thermophysical characteristics, anisotropy, inverse problem.
