Abstract:

Purpose: The purpose of the paper is to present the material and technological solution which makes possibleobtaining soft and hard magnetic composite materials: nanocrystalline material – polymer.Design/methodology/approach: The main base of the paper is to compare the structure and mechanicalproperties of chosen magnetic composite materials with polymer matrix reinforced with Nd-Fe-B or FINEMETparticles manufactured by one-sided uniaxal pressing. The complex relationships among the manufacturingtechnology of these materials, their microstructure, as well as their mechanical and physical properties wereevaluated.Findings: Modern magnetic materials have optimum technology of production with properties that allow forminiaturizing, simplification and lowering the costs of devicesPractical implications: The manufacturing of composite materials greatly expands the applicable possibilitiesof nanocrystalline powders of magnetically hard and soft materials however further examination obtainimproved properties of magnetic composite materials. The investigations of constructing of new machines anddevices with these materials elements are still needed.Originality/value: The paper shows the base of the material and technological solution which make possibleobtaining magnetic composite materials and their mechanical properties which are not commonly presented inother papers.
