The paper presents the results of studies of thermophysical properties: heat capacity, thermal conductivity, thermal diffusivity and heat storage ability of polymeric polymer composite materials. A method is proposed for determining these properties, based on the well-known method for determining thermophysical properties by eliminating variables. The experimental values of the thermophysical properties of polymer composite materials with the addition of powder particles of various fractions of aluminium, iron, carbon and copper are obtained. The effectiveness of the proposed method is shown by comparing the known values of the specific heat and thermal conductivity of polyurethane with experimental.
