One of the important properties of reinforced composite polymer materials is their physico-chemical properties. Their structure plays an important role in assessing the physico-chemical properties of composite materials. Research objectives - to study the physico-chemical properties of high-strength polymer composite materials.
Experiments were carried out at 100 and 400-fold magnification in an optical microscope to study the morphology and structural changes of various parts of high-strength polymer composite materials with a polymer binder - ED-20 and nitrone fibers. IR spectroscopic studies were also carried out to study the interaction of nitron fibers with an epoxy binder - ED-20 during the formation of high-strength polymer composite materials. The data obtained in the study of various sections of polymer composites revealed a linear structure characteristic of nitron fibers coated on all sides with a polymer binder - ED-20, and structural changes in morphology at 100 and 400-fold magnification. Infrared spectral studies showed that the intermolecular interaction between hydroxyl and amide groups was established as a result of the interaction of the nitrile groups of the nitrone fiber and ED-20 with PEPA. Based on the analysis of the results obtained, it can be concluded that the developed composite materials based on epoxy binders with nitrone fibers can be considered as a new class of composite materials designed to operate under high stress conditions.
