Установлен средний модуль упругости пленки в упругой стадии, который составил 35,8 МПа, при последующем загружении происходит переход к упругопластичной и пластичной стадиям работы с понижением модуля упругости сначала до 1,78−2,71 МПа и затем до 0,06−0,086 МПа. Силовые испытания мембраны из пленки из этилен-тетрафторэтилена толщиной 250 мкм на силовой треугольной раме при равномерно распределенной нагрузке 8,577 кПа не привели к разрыву мембраны ни при положительных (+15…+18 °С), ни при отрицательных температурах (−23…−29 °С). Многократное механическое повреждение мембраны под нагрузкой 8,50 кПа при температуре −26 °С не привело к ее разрыву. Прогибы мембраны при положительных температурах достигали 84 мм, при отрицательных температурах ‒ 58,2 мм. Испытания пленки показали ее сверхвысокие прочностные характеристики и на перспективность широкого использования пленки из этилен-тетрафторэтилена для создания комфортной среды в сооружениях, возводимых в Арктике и на других территориях России.</p></abstract><trans-abstract xml:lang="en"/><kwd-group xml:lang="ru"><kwd>силовые испытания</kwd><kwd>пленка ЭТФЭ</kwd><kwd>мембрана</kwd><kwd>механическое повреждение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanical strength testing</kwd><kwd>polytetrafluorethylene</kwd><kwd>ethylene-tetrafluo- roethylene film</kwd><kwd>membrane</kwd><kwd>elastic modulus</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено по заказу ФГУП «ГНПП «КРОНА» по теме «Поиск, исследование и анализ решений несущих, ограждающих конструкций и оснований для создания большепролетных климатических искусственных укрытий для условий районов Крайнего Севера и вечной мерзлоты» и при финансовой поддержке Министерства науки и высшего образования РФ по проекту FEMN-2020-0003</funding-statement><funding-statement xml:lang="en">The study was commissioned by the Federal State Unitary Enterprise “GNPP “KRONA” on the topic “Search, research and analysis of solutions for load-bearing, enclosing structures and foundations for creating large flight climatic artificial shelters for the conditions of the regions of the Far North and eternal permafrost” and with the financial support of the Ministry of Science and Higher Education of the Russian Federation for project FEMN-2020-0003</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Новое в технологии соединений фтора : пер. с японск. / под ред.
