EXPERIMENTAL AND THEORETICAL INVESTIGATION OF THERMOPHYSICAL AND MECHANICAL PROPERTIES OF THE EPOXY-CLAY NANOCOMPOSITE

摘要

The paper generalizes results of complex research of mechanical and thermophysical properties of epoxy-based nanocomposites (NC). The kinetics of moisture absorption of epoxy matrix and epoxy-based NC were previously studied experimentally. The mechanical properties of NC were experimentally investigated in tensile quasistatic and creep tests. Application of dilatometry analysis allowed establishing basic regularities for glass transition temperature for NC. The interrelation of thermophysical and mechanical characteristics of epoxy-clay NC having absorbed moisture was estimated with the structural changes accompanying deformation at various schemes of loading and temperatures.
