Abstract

Processes of sorption and desorption of moisture by epoxy polymeric matrix and layered carbon fiber on its basis are considered. Moisture diffusion factors are estimated on stages of sorption and desorption. The conclusion is drawn on nature of diffusion in epoxy matrix and in polymeric composite material, on the basis of this matrix. The qualitative analysis of epoxy matrix, in the course of moisture sorption, is carried out by FTIR Spectroscopy. The structure and energy of molecule of epoxy matrix is calculated, at absence and presence of the bonded moisture in its composition. Researches of mechanical properties of polymeric composite materials are conducted at different values of moisture content. Changes of thermophysical properties of layered carbon fiber in the course of moisture sorption and desorption are investigated.
