Abstract

This paper presents studies on the change in the durability of carbon fiber reinforced plastic during moisture sorption. For this purpose, at different stages of material moistening and in the dried state of it, short beam shear tests at loading rates differing by 3–4 orders of magnitude, cyclic tension-compression tests with increasing loading amplitude and a dynamic mechanical analysis were carried out. The study shows that the strength properties and the glass transition temperature of the carbon fiber reinforced polymer with different moisture content conform to the temperature-humidity analogy and ramp-down with the increase of moisture content.
