FIELD: composite materials.

SUBSTANCE: invention relates to powder technologies for the production of solid bulk composite materials based on quasicrystals. A composite material based on a quasi-crystalline powder of the Al-Cu-Fe system contains a nickel bond in the form of a uniform reinforcing nickel mesh with a nickel content in the composite not exceeding 3 wt.%. The method for producing a composite material includes applying a nickel coating to quasicrystal powder particles of the Al-Cu-Fe system, pressing the nickel-coated powder at a pressure of more than 1.5 GPa, and annealing the compressed powder at a pressure of less than 100 MPa in a reducing or inert atmosphere or in a vacuum at a temperature not exceeding 850 K.

EFFECT: invention is aimed at obtaining bulk full-dense composite quasi-crystalline materials with high mechanical properties, a reduced coefficient of friction and increased resistance to mechanical wear.
