Magnetic nanocomposite materials: structure and mechanical properties

Composite materials reinforced by Nd-Fe-B (hard magnetic material) or FINEMET (soft magnetic material) particles with polymer matrix were manufactured by one-sided uniaxial pressing. The complex relationships among the manufacturing technology of these materials, their microstructure, as well as their mechanical and physical properties were evaluated. The main purpose of obtaining this kind of composite materials is broadening possibilities of nanocrystalline magnetic materials application that influence on the miniaturisation, simplification and lowering the costs of devices. The manufacturing of composite materials greatly expand the applicable possibilities of nanocrystalline powders of magnetically hard and soft materials. However, further examination to obtain improved properties of magnetic composite materials and investigations of constructions of new machines and devices with these materials elements are still needed. This paper shows the base of the technological solution which makes it possible in obtaining magnetic composite materials and mechanical properties of these composite materials.
