The basic mechanical characteristics (yield stress, strength and total deformation to failure) of films are determined at these temperatures. It is shown, that at the room temperature polytetrafluorethylene and fluoroplast have high total deformation to failure, but already at temperature of liquid nitrogen polytetrafluorethylene finds out brittle failure, and fluoroplast F-4 shows sharp decrease in total deformation.Values of blackness factors of the investigated materials are defined at room temperature.The technique of an irradiation of polymers by protons and electrons in the complex simulator of space factors is advanced.5481 Product Description popup.authors Абраімов Вячеслав Володимирович Волобуєв Федір Іванович Заіка Олександр Сергіойвич Зарицький Іван Петрович Сальтевський Григорій Іванович popup.nrat_date 2020-04-02 Close
