Beschreibung
Zusammenfassung:	The invention relates to the polymeric composite materials on the basis of epoxy binding agent, which is reinforced by fibrous filler. In the proposed method, the heating of articles made of polymeric composite materials is carried out by an electromagnetic field of ultrahigh frequency of entire volume of liquid binding agent at temperatures of 120-160 DEGREE C. The method ensures the considerable decrease of hardening time, the improvement of mechanical properties, it decreases the local stresses in the structure, and prevents crack formation and stratification.
