Исследованный материал состоит из трех слоев углеродной биаксиальной ткани Ст 12073, пропитанных полимерной матрицей Diaplex MP5510 на основе полиуретана. Данный материал предназначен для изготовления шпангоута, применяемого в конструкции прецизионного композитного рефлектора космической антенны. Шпангоут при раскрытии рефлектора в транспортное положение принимает ранее заданную форму посредством нагрева, что позволяет увеличить жесткость оболочки рефлектора на периферии и повысить точность отражающей поверхности. Для изучения функциональных и механических свойств материала шпангоута при его изготовлении и различных режимах работы были проведены испытания образцов с различными схемами армирования: [<xref ref-type="bibr" rid="cit03">03</xref>], [0/±60] и [0/±45]. Исследовали степень фиксации, степень восстановления и скорость восстановления формы в зависимости от схемы армирования, скорости деформирования и времени выдержки в деформированном состоянии. Для этого была разработана программа испытаний образцов, которая включала несколько этапов. На первых этапах проводили испытания на фиксацию и восстановление формы при трехточечном изгибе плоских образцов при скоростях деформирования 1,5 и 10 мм/с и времени выдержки в деформированном состоянии в течение 24, 48 и 96 ч. По результатам испытаний материал со схемой армирования [<xref ref-type="bibr" rid="cit03">03</xref>] принят как оптимальный для изготовления шпангоута, поскольку имел максимальные степень и скорость восстановления формы. Для выбранного материала на заключительном этапе исследований определяли модуль упругости и предел прочности при различных температурах эксплуатации шпангоута: –50, +20 и +60 °C. Проведенные исследования показали, что исследованный композитный материал обладает требуемым эффектом памяти формы и является перспективным для изготовления шпангоута при условии применения теплоизоляции.</p></abstract><trans-abstract xml:lang="en"><p>Experimental study of the shape memory polymer composite is carried out as a part of scientific and technological work aimed at development of the new promising reflectors for space antenna. The studied material consists of three-layered carbon biaxial fabric St 12073 impregnated with a polyurethane-based Diaplex MP5510 polymer matrix. This material is intended for manufacturing a frame used in the construction of a precise composite reflector of space antenna. When opening the reflector to the transport position, the rim activated by heating recovers a previously specified shape thus increasing the rigidity of the reflector at the periphery and enhancing the accuracy of the reflecting surface. To study the functional and mechanical properties of the rim material in manufacturing and operating conditions, experimental tests were carried out on the samples with different schemes of reinforcement: [<xref ref-type="bibr" rid="cit03">03</xref>], [0/±60] and [0/±45]. The main goal of the study is to determine the degree and rate of the shape recovery, reinforcement angles, deformation rate and exposure time in the strained state. The developed test program included several stages. At the first stages, tests were carried out for fixing and restoring the shape upon three-point bending of flat samples at a strain rate of 1, 5, and 10 mm/sec and exposure of the specimens in deformed state for 24, 48, and 96 h. According to the results the material with the reinforcement angles [<xref ref-type="bibr" rid="cit03">03</xref>] was accepted as optimal for the rim design, as it has maximal shape recovery parameters. For the selected material at the final stage of the study, the elastic modulus and tensile strength were determined at operating temperatures –50, +20, and +60°C. The tests showed that the studied polymer composite material has the desired shape memory properties and is promising for the rim manufacturing provided the heat insulation during operation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>композитный материал</kwd><kwd>память формы</kwd><kwd>рефлектор</kwd><kwd>испытания</kwd><kwd>механические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composite material</kwd><kwd>shape memory</kwd><kwd>reflector</kwd><kwd>testing</kwd><kwd>mechanical properties</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Meng H., Li G.
