The physical-mechanical, thermophysical, and other important properties of polymer composites primarily depend on the polymer fillers used as modifiers. Examples of fillers include substances that act as structural modifiers, additives, mineral additives, and so on. As studies conducted in this area show, modifiers for various purposes are used to improve chemical and physical-mechanical parameters. The article provides information about the development and production of polymer composite materials. The possibility of obtaining and using composite materials in various fields of technology is shown. In addition, a review of studies that provide a broad understanding of polymer composite materials is also collected. It has been shown that the use of polymer composite materials can lead to significant advances in modern manufacturing. The article also provides information on or-ganic and inorganic fillers with different properties. Based on this, the results of studies carried out in the direction of obtaining polymeric materials using carbon, carbon graphite, fiberglass, etc. are summed up. The nanocomposites of the new generation demonstrate innovative results. This paper shows innovative applications of polymer composite materials for various purposes. All this makes it possible to use the rich mineral resources of Azerbaijan in the production and operation of polymer composite materials
