This study investigates the structural and physicochemical transformations occurring in polyamide-based composites reinforced with iron oxide nanoparticles, with the aim of developing advanced materials for mechanical engineering applications. Polyamide-52 (PA-52) was selected as the polymer matrix due to its favorable strength, tribological performance, and low density compared to traditional metals. Despite its advantages, PA-52 exhibits reduced mechanical properties in humid environments and limited dimensional stability, which necessitates modification through functional fillers.To improve the performance characteristics, iron oxide (FeO) nanoparticles were introduced into the polymer matrix using controlled dispersion techniques. X-ray fluorescence (XRF) analysis was employed to determine the elemental composition of neat PA-52 and PA-52/FeO composites. The results confirmed the presence of non-metallic and metallic oxides—including iron, magnesium, manganese, germanium, zinc, and trace elements—in varying proportions, indicating the individuality of the modified composite. Further structural identification was performed using X-ray phase analysis (XRD). Comparative diffraction patterns demonstrated distinct interplanar spacings and intensity ratios for PA-52 and PA-52 with FeO nanoparticles, revealing significant changes in crystallinity and structure formation. The introduction of FeO altered the supramolecular organization of the polymer matrix, intensifying diffraction peaks and modifying the structural ordering. The results indicate that FeO nanoparticles play an active role in enhancing the structural properties of polyamide composites, making them suitable for use in high-demand mechanical systems. The study provides a scientific basis for the development of new-generation polymer composites with predictable and improved performance characteristics for the engineering industry.
