Abstract

Various standards for determining the glass transition temperature by dynamic mechanical analysis and the dependence of the dynamic modulus of elasticity on temperature are considered. Two melt-type epoxy binders with similar values of glass transition temperature, but different nature of the drop in the dynamic modulus of elasticity upon heating, were selected. Samples were made, a tensile test was carried out, after which the polymer matrices were evaluated using various standards and the results were compared.
