    ENG: The development of hypersonic unmanned aerial vehicles (UAVs) for aerospace systems presents ambitious challenges for scientists and engineers. Extreme flight conditions, such as ultra-high speeds and significant aerodynamic heating, necessitate the creation of new materials capable of withstanding such loads. One of the most promising materials for constructing hypersonic UAVs is carbon fiber-reinforced polymer based on bisphenol nitrile. This material exhibits high thermal resistance, chemical stability, and excellent mechanical properties. Utilizing bisphenol nitrile combined with carbon fibers has enabled the production of composite materials that can operate at temperatures exceeding 300 оC, far surpassing the capabilities of traditional polymer matrices. To assess the suitability of the developed carbon fiber-reinforced plastic for hypersonic UAV applications, comprehensive studies of its physical, mechanical, and thermal characteristics were conducted across a wide temperature range from 20 to 300 оC. The obtained results provided a detailed characterization of the composite and allowed for comparisons with other high-temperature composite materials. The developed carbon fibre-reinforced plastic based on bisphenol nitrile binder shows great promise for constructing hypersonic UAVs. Its high thermal resistance, combined with excellent mechanical properties, makes it suitable for use in the extreme temperature conditions typical of hypersonic flight.

    Production of Fiberglass Plastics Using Infrared Heating
    (Український державний хіміко-технологічний університет, Дніпро, 2025) Manko, T.; Husarova, I.; Kozis, K.; Sukha, Iryna V.; Zaichuk, Oleksandr V.; Sukhyy, Kostyantyn M.
    ENG: This study analyzes the technology for creating polymer composite materials reinforced with glass fiber. Particular attention is given to their applications in the aerospace industry, where stringent requirements for strength, corrosion resistance, and specific strength render these materials indispensable. The main components of composite materials and their properties are examined. Phenol-formaldehyde resins, widely utilized as a matrix for fiberglass plastics in rocket and space engineering, are studied in detail. The thermomechanical resistance of composites, a critical factor determining their performance under extreme conditions, is highlighted. A significant part of the study focuses on the production and curing processes of composite materials. Various curing methods are analyzed, with a focus on the effectiveness of infrared radiation. The findings establish that infrared heating significantly enhances the physical and mechanical properties of composites while reducing production time.
