Appropriate techniques and experimental equipment for CM tests was developed. The thermal expansion coefficients, characteristics of strength and deformability of CM are determined. The analysis and limitations for generalized phenomenological criterion of macrofracture CM for engineering applications has been made. A numerical simulation of monolayer of carbon fiber and a polymer base did not reveal a reliable formula for calculating Young's modulus in directions perpendicular to the main direction when the Young's modulus of individual components of the monolayer, measured in the main direction and weight fractions of these components was given. Therefore, to reduce the "unavoidable" error in the monolayer Young's modulus calculations, it is advisable to use a full-scale experiment. Based on the calculations, a refined and simplified method for determining the "equivalent" characteristics of the honeycomb panel model in the form of 6 planes (HEXCEL) cells has been proposed Product Description popup.authors Бабак Антон Миколайович Бондарець Олександр анатолійович Коваль Віктор Вікторович Куан Фам Дик Рудаков Констянтин Миколайович Тимошенко Олександр Вікторович popup.nrat_date 2020-04-02 Close
