Abstrakt: An urgent problem in improving polymer-based tribotechnical materials is to reduce the friction and wear coefficients with preservation of sufficiently high physicomechanical characteristics of material. This review covers the studies devoted to the preparation and analysis of tribological, deformation-strength, and thermophysical properties, as well as the structure and morphology of composites based on polymer matrices of ultra-high molecular-weight polyethylene (UHMWPE), polytetrafluoroethylene, and ethylene– tetrafluoroethylene copolymer, filled with quasicrystalline (QC) Al–Cu–Fe powder, which were carried out at the National Research Centre "Kurchatov Institute." These studies were aimed at obtaining and analyzing information in order to gain a deeper insight into the processes occurring in materials subjected to friction and search for promising combinations of materials in the matrix–filler pair. Good prospects of application of QC Al–Cu–Fe powder as a filler are justified. [ABSTRACT FROM AUTHOR]
