FIELD: process engineering. ^ SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of polymer-metallic composite materials. It may be used for making magnetically soft materials for cores of inductors, stators and rotors of electric machines. Powder composition with lubing material is compacted to make billet to be heated to above lubing material evaporation temperature so that said material is, mainly, removed from compacted billet. Billet thus made is subjected to action of liquid polymer composite containing nano- and/or micro sized reinforcing structures and cured by drying and/or hardening. Produced composite part is formed by interpenetrating polymer networks between powder composition and polymer composite while reinforcing structures comprise one or several components selected from particles, plates, fibers, whiskers and tubes. ^ EFFECT: higher density and strength at higher temperatures, better machining properties. ^ 25 cl, 5 tbl, 8 ex |
