The article presents a review of the scientific and technical information from Russian and foreign periodicals, patents for inventions in the field of using various materials for the production of prepregs. Data on global manufacturers and applied technologies are provided. Prepreg is a polymer composite material based on carbon or glass fabrics. The technology for its production consists in impregnating the reinforcing material with a special binder. Typically, it is the resin in an uncured or partially cured state. Particular attention to polymer composite materials based on glass fibers is paid. The binder is a solution of organic substances, which is used as an impregnating agent. The combination of fibrous fillers and impregnating composition makes it easy to shape the final product. It is showed that the main areas of prepreg applications are the automotive industry, construction, transport, sports equipment, as well as various sectors of the national economyThe composite materials are shown to have a number of advantages, including economic ones. According to the conducted scientific and patent search, the most common components of polymer composite materials are epoxy resin and various types of hardeners.
