The paper considers the opportunity for investigation of the thermal field in two-component systems of the type of polymeric composite materials with continuous fibrous filler. In view of the widespread use of polymer composites high relevance of issues relating to their processing. Is a literary analysis of shortcomings of the thermophysical properties of polymer composite materials, arising in the process of machining. The author suggests a method of investigation of thermal processes in complex anisotropic bodies, do not have an analytical solution without primary assumptions that affect the accuracy of these decisions. The method consists in reducing the geometry of the investigated object to this simple structure duplicating that you can get the source object. Created and step-described computer model of the thermal field of structural phases of polymer composite material in an elementary volume. The definition of the process of heat distribution on the surface and on the axis of an individual fiber and unit cell. The researchers calculated that the maximum temperature occurs at the surface of a polymer matrix and considerably differs from the temperature on the surface of the fiber. By isothermal analysis revealed the thermal effect of the polymer matrix on the fiber. In the modeling process, identifies factors affecting the formation of the temperature field in the unit cell material, among them: thermophysical properties of the components, their volume content, geometrical parameters and orientation relative to each other.
