INVESTIGATION OF THE EFFECT OF MOISTURE ON POLYMER COMPOSITES BY THE METHOD OF THERMOGRAVIMETRY T. A. Starzhenetskaya and N. N. Davydova UDC 620.193:678.067-419 We present results of an experimental study of absorption of moisture by epoxy resin-based polymer composite materials by the method of thermogravimetry. We established quantitative parameters of the reversibility of the sorption-desorption process for the composites investigated and the diversity of the states of the water sorbed.
