Abstract

The second section of the article presents the results of studies of the coefficient of linear thermal expansion (CLTE) of carbon fiber reinforced plastic based on the cyanoether binder VSC-14, exposed for 24 months in a moderately cold climate and laboratory simulation conditions. Two variants of full-scale climatic tests were studied: standard exposure on an open atmospheric stand and exposure with a combination of thermal cycles simulating the mode of takeoff and landing of an aircraft. To find out the reasons for the change in the CLTE, the results of measurements of the compressive and tensile strengths, as well as the glass transition temperature of the binder VSC-14, are analyzed.
