Problems of polymer matrix reinforcement with dispersed fillers and creation of high-strength composite materials

The main stages of the development of ideas about the processes leading to the strengthening of dispersed-filled polymer composite materials (PCM) are considered. The latest experimental data on the structure of filled PCM are presented, and ideas about the mechanism of their strengthening are formulated. The prospects of using inexpensive natural minerals as strengthening fillers for polymer matrices are shown, provided that strong chemical bonds are formed at the polymer-filler interface.
