<p>In this study, the tribological properties of epoxy composites reinforced with low concentrations of Ti₃SiC₂ MAX phase particles (1, 5, and 10 wt.%) were investigated under dry sliding conditions at room temperature. Tests were conducted using normal loads of 5 N, 7 N, and 10 N. The epoxy/10 wt.% Ti₃SiC₂ exhibited self-lubricating behavior, achieving the lowest friction coefficient of 0.29 and a negligible wear rate under 10 N load, demonstrating the composite's ability to reduce friction and maintain high wear resistance even under high loads. Compared to neat epoxy, the friction coefficient decreased by 43%, and the wear rate was reduced by at least more than 200-fold. For comparison, epoxy reinforced with 10 wt.% TiC was fabricated. The incorporation of TiC particles drastically deteriorated the wear resistance of epoxy resin. The superior performance of Ti₃SiC₂ compared to TiC is attributed to its strong coherence with the epoxy matrix, enabling excellent filler distribution and promoting the formation of lubricating and anti-wear films on the sliding surfaces. The findings suggest potential directions for development of lighter and more efficient materials for industrial devices and functional applications.</p>
