Abstract

The aerospace industry is currently undergoing a major trend of transitioning to composites. This study exanines the utilization of the magnetic field of rotating dipoles to produce high-strength iron powder-containing composites. The physical and mechanical properties of the modified epoxy composites were investigated through the use of SEM to analyze their microstructure and elemental composition, and a component distribution map was developed for the samples. Results indicate that the application of the magnetic field of rotating dipoles enhances the compression strength by 16.6 % relative to samples that were not exposed to it. Additionally, the magnetic field eliminates gas porosity and cavities formed during stirring. Tests conducted on composites with a higher content of Al particle showed that the magnetic field of rotating dipoles contributes to the release of excess aluminum as a surface layer. The use of the magnetic field of rotating dipoles is a promising technology for producing enhanced composites with superior physical and mechanical properties, which could potentially be used as structural material in aerospace industry or as adsorbing materials in microelectronics.
