In recent decades, quasicrystals have found wide application in the production of new composite materials due to their unique properties. In particular, Al–Cu–Fe based systems exhibit outstanding mechanical properties, including increased hardness and wear resistance.

Such compositions are prepared by mixing quasicrystalline Al–Cu-Fe powder with an epoxy matrix. This process typically includes mechanical mixing, curing and heat treatment steps to ensure optimal dispersion of the quasicrystals in the matrix.                                                    

The wear resistance of quasicrystalline epoxy composites is determined by their high hardness values ​​and low friction coefficients, which makes them promising for use under high load conditions, for example, in mechanisms and friction units.

Studies have shown that such composite materials can significantly extend the service life of parts, which can reduce operating costs and increase the reliability of various industrial systems. Further research in this area is aimed at optimizing the composition and production processes to achieve maximum strength and wear resistance.
