Abstract
The method of free torsion vibrations was used in the temperature range of 77–470°K to examine the effect of adsorbed moisture on dynamic properties of compositions based on an epoxide binder, reinforced with an organic fibre. It was found that water when exceeding the limit of compatibility with polymer has an unusual effect on dynamic mechanical characteristics of the composition in a wide range of temperature. A study was made of the molecular mechanism of α- and β-relaxation processes dependent on the interaction of macromolecules of the binder with adsorbed water molecules.
