Purpose: The purpose of the paper is to present the technological solution of obtaining hard magnetic composite materials based on Nd-Fe-B with addition of iron powder and bounded by epoxy resin. Design/methodology/approach: Composite materials reinforced by Nd-Fe-B particles or Nd-Fe-B with addition of iron powder with polymer matrix were manufactured by one-sided uniaxal pressing. The complex relationships among the manufacturing technology of these materials, their microstructure, as well as their magnetic and mechanical properties were evaluated. Findings: This kind of composite materials can broader the possibilities of application of magnetic materials and reduce the cost of their manufacturing. Practical implications: The manufacturing of hard magnetic composite materials by addition of other powder and bounding them by polymer matrix can greatly extend the applicable possibilities of these materials. There are still made investigations that allow to improve properties of hard magnetic composite materials and influence on the miniaturization of magnets and devices they are used in. Originality/value: The paper shows the technological solution which make it possible obtaining hard magnetic composite materials, their structure and properties.
