The paper studies the thermal conductivity and specific heat capacity of carbon fiber reinforced plastic (CFRP) with various reinforcements using the methods of a stationary heat flow (SHF) and differential scanning calorimetry with temperature modulation. The values of the thermal conductivity and heat capacity, as well as their dependence on temperature, are established in the temperature range from –20 to 100°C. The changes in the thermal conductivity range from 0.400 to 0.515 W/(m K); and the specific heat capacity coefficient, from 923 to 984 J/(kg K). The results obtained can be used to calculate and design systems and installations using PCMs as structural materials and to calculate the parameters of the technological process for the production of these materials.
