- Аннотация: —Samples of composites of ultra-high molecular-weight polyethylene (UHMWPE) with addition of 2.24, 5, and 8.1 wt % quasicrystalline Al–Cu–Fe alloy have been prepared by in situ polymerization. Friction and wear tests are performed, the physico-mechanical tensile properties are studied, and the thermophysical properties are investigated using differential scanning calorimetry and thermogravimetric analysis. The surface morphology of composite samples, both subjected and not subjected to friction, has been investigated by scanning electron microscopy. It is found that addition of a quasicrystalline Al–Cu–Fe filler in amount of 2.24 wt % improves the tribological characteristics of UHMWPE: under a load of 50 N and at friction duration of 8 h, the wear decreases by a factor of 3, and the friction coefficient decreases by 20%.
