The invention relates to powder techniques for producing solid three-dimensional materials. The technical result of the invention consists in improving the characteristics of the three-dimensional materials produced and creating additional possibilities for new technological applications by improving the properties of said materials. The technical result is achieved with the aid of a composite material based on a quasicrystal powder of an Al-Cu-Fe system with a nickel binder, said composite material containing a reinforcing nickel lattice, and is achieved by the fact that a nickel coating is applied to quasicrystal powder particles of an Al-Cu-Fe system (to this end, the quasicrystal powder is advantageously treated in plasma, as a result of which a thin (10-20 nm) nickel coating forms onthe surface of the powder particles). The treated powder, which is a dispersed composite material, is then pressed at room temperature under quasi-hydrostatic conditions at a pressure of more than 1.5GPa. Using the method dev
