Abstract

The study aimed to investigate changes in the properties of carbon-fiber reinforced plastic VKU-39/VTkU-2.200 after six months of exposure in the temperate and warm climate of Gelendzhik. Various analysis methods, such as profilometry, gravimetry, thermomechanical analysis, and dynamic mechanical analysis, were used for this purpose. Additionally, interlayer shear tests using the short beam method and longitudinal bending at different loading speeds were conducted. Based on the results of these tests, a thermal activation analysis was performed, which showed high sensitivity in determining durability at an early stage of weathering.
