Physical-mechanical, thermally conductive and electrically conductive properties of the heat-conducting composite materials (CM) based on epoxy and polyester resin are practically independent on the polymer matrix but determined by the nature and content of fillers. The introduction of the graphite into CM leads to an increase in thermal conductivity and has no influence on the strength characteristics. The strength characteristics of CM are increased when reinforcement with fiberglass however its use leads to increased electrical resistance. The introduction of two layers of fiberglass in CM leads to an increase of electrical resistance by two times. For the development of thermally conductive CM can be equally effectively used as epoxy and polyester resin. From the point of view of economic effectively it is advisable to use polyester resin.
