The work is devoted to investigation of polymer material structure and revealing its dependence on conditions and regime of processes occurring at the moment of polymer matrix curing and deformation, as well as the influence of filler and its adhesion to polymer matrix. Initial diagnostics of the structure of glass-reinforced plastic based on epoxy binder ED-20 and glass fabric TR-560-30A (100) was carried out in the experiment to further study the effect of very cold climate of Yakutsk on the strength and deformation characteristics of the composite material.
