Abstract

A comprehensive assessment of the durability of the strength properties of carbon fiber grade VKU-51 under tension, compression and bending in the temperature range from –60 to +80 °C in the initial state and after after climatic tests in a tropical climate and heat-humidity aging chamber to operating factors such as in a tropical climate chamber and heat-humidity aging for 1 and 3 months, as well as thermal aging for 500, 1000, 1500 and 2000 hours was carried out. The influence of mycological environment and fuel and lubricants of automobile fluids on the bending strength limit of carbon fiber reinforced plastic and weight gain was studied.
