Abstract

Using the methods of thermogravimetry, analysis of 3D images of the surface topography and kinetics of moisture transfer, the mechanism of thermal aging and physicochemical transformations under the influence of elevated temperatures in carbon fiber reinforced plastic VKU-38TR is studied. According to the results of profilometry, it was proved that the degree of destruction of the surface layer of the studied carbon fiber reinforced plastic depends on the duration of exposure to the operating temperature and its value. The significant effect of thermal aging on the moisture absorption of carbon fiber reinforced plastic is shown.
