ABSTRACT

Aiming to control by stress birefringence the radiotransparent fiberglass plastic products based on highly cross-linked polymer matrices, theoretical regularities for mathematical description of this property were developed. Computer physical modeling of topological structure of experimental objects was carried out on epoxy-amine polymers with different cross-link density taken as an example. And constants of this model were specified. The adequacy of the model was demonstrated by comparison of the model-calculated against experimental approach to thermal polarization curves.
