Abstract

A comprehensive assessment of the retention of strength properties of carbon fiber plastic of the VKU-59 brand under tension, compression, bending, interlayer shear at test temperatures of –60, +20, +80 and +105 °C was carried out in the initial state and after climatic influences in a tropical climate chamber for 1 and 3 months, heat and humidity aging for 1 and 3 months, thermal aging for 500 and 1000 hours. The influence of the mycological environment and process fluids on the tensile strength of carbon fiber reinforced plastic in bending and compression was studied. To confirm the viability, samples of VKU-59 carbon fiber plastic were tested in tension and compression after 3 months of storage.
