Цель работы – исследовать влияние натурного экспонирования углепластика (УП), базальтопластика (БП) и стеклопластика (СП) в условиях Якутска на теплопроводность, динамико-механические и термомеханические характеристики и сопоставить наблюдаемые изменения с типичной термоциклической нагрузкой региона. Температуру поверхности ламинатов регистрировали на солнечной и теневой сторонах; свойства материалов оценивали методами измерения теплопроводности, динамического механического и термомеханического анализа. Дополнительно анализировали переходы температуры через 0, –18 и –33 °C. За 2023–2024 гг. число таких переходов для УП/БП/СП составило соответственно 489/468/438, 298/287/262 и 166/163/163; эти значения рассматриваются как характеристика типичной термоциклической нагрузки Якутска. УП характеризовался наиболее высокой теплопроводностью и более равномерным температурным полем. После экспонирования его динамический модуль увеличился, а температура стеклования сместилась в область более высоких температур. Для БП отмечены умеренные изменения жесткости и термомеханических характеристик. СП проявил наиболее выраженную зависимость от стороны экспозиции и максимальный температурный градиент между солнечной и теневой поверхностями, достигавший 11,8 °C. Полученные результаты показывают различную климатическую устойчивость исследованных ПКМ и указывают на существенный вклад термоциклических воздействий, влажности и солнечного нагрева в изменение их свойств. Эти данные могут быть использованы при оценке долговечности композиционных материалов в арктических условиях.</p></abstract><trans-abstract xml:lang="en"><p>Polymer composite materials (PCMs) used in cold climates require assessment of their resistance to repeated temperature fluctuations and associated structural changes. This study investigates the effect of two-year outdoor exposure in Yakutsk on the thermal conductivity, dynamic mechanical, and thermomechanical properties of carbon-, basalt-, and glass-fiber-reinforced polymers (CFRP, BFRP, and GFRP, respectively), and compares the observed changes with the typical thermal-cycling load of the region. For this purpose, surface temperatures were monitored on the sun-exposed and shaded sides, and material properties were evaluated by thermal-conductivity measurements, dynamic mechanical analysis, and thermomechanical analysis. Temperature transitions through 0 °C, –18 °C, and –33 °C were also analyzed. During the 2023–2024 exposure period, the numbers of such transitions for CFRP, BFRP, GFRP were 489/468/438, 298/287/262, and 166/163/163, respectively; these values characterize the typical thermal-cycling load in Yakutsk. Regarding material performance, CFRP exhibited the highest thermal conductivity and a more uniform temperature field; after exposure, its dynamic modulus increased and the glass-transition temperature shifted to higher values. BFRP showed moderate changes, whereas GFRP displayed the strongest dependence on the exposed side and the largest temperature gradient between the sun-exposed and shaded surfaces, reaching 11.8 °C. Overall, these results demonstrate different climatic resistance among the studied PCMs and indicate the contribution of thermal cycling, moisture, and solar heating to changes in their properties, thereby providing a basis for durability assessment under Arctic conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полимерный композиционный материал</kwd><kwd>холодный климат</kwd><kwd>термоциклирование</kwd><kwd>внутренние  напряжения</kwd><kwd>углепластик</kwd><kwd>стеклопластик</kwd><kwd>базальтопластик</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polymer composites</kwd><kwd>cold climate</kwd><kwd>thermal cycling</kwd><kwd>internal stresses</kwd><kwd>carbon fiber reinforced plastics</kwd><kwd>glass fiber reinforced plastics</kwd><kwd>basalt fiber reinforced plastics</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 25-69-00009,  https://rscf.ru/project/25-69-00009/.</funding-statement><funding-statement xml:lang="en">This research was funded by the Russian Science Foundation (grant No. 25-69-00009, https://rscf.ru/ project/25-69-00009/).
