“…Ранее авторы статьи провели серию экспериментов [1] на растяжение и изгиб с целью определения физико-механических свойств поликарбоната в стандартных условиях. Также результаты экспериментальных исследований по определению различных физических, механических, оптических и других свойств монолитного поликарбоната приведены в [2][3][4][5][6][7][8][9][10]. При этом прочностные и деформационные характеристики этого материала как одного из вида пластмасс зависят от температурного режима эксплуатации элементов конструкций [11; 12].…”

The study of the physical and mechanical properties of polycarbonate under various temperature conditions, taking into account its widespread use as a base material of monolithic polycarbonate systems in various climatic regions, will ensure a high degree of reliability of structures during operation in a wide temperature range. The authors of the article conducted a series of tensile tests of monolithic polycarbonate in the temperature range from -60 to +80 °C. The influence of temperature on the following characteristics of monolithic polycarbonate was evaluated: elongation at break, tensile yield strength, tensile stress at break, strains at the end of the elastic stage of the material. As a result of the conducted experimental studies, the relationship between the strength properties of monolithic polycarbonate and the operating temperature was revealed. The values of elongation at break at temperatures exceeding 15 °C for various samples generally correspond to the values obtained during tests conducted under standard conditions.
