The article discusses the elements of technology and methods of physical modification of polymers. Recommendations have been developed for the selection of components and individual elements of the technological process for the production of a composite material based on glass fabric with improved mechanical characteristics. The processes and dependences of the influence of the properties of individual components of the composite on the mechanical properties of the material as a whole are presented. The analysis of methods of physical modification of polymers was carried out, the most acceptable options were selected. Their comparative characteristics are carried out, the possibility of their application in the technological process is considered. The dependences of the mechanical characteristics of the polymer epoxy matrix on the duration of its irradiation with ultraviolet radiation during polymerization are shown, during which the effectiveness of this method is experimentally confirmed. Dependences reflecting the nature and degree of influence of the duration of ultraviolet irradiation of an epoxy polymer on its mechanical properties are obtained.
