摘要：

Tribological performance of epoxy (EP) composites reinforced with short glass fibers (SGF), graphite, polytetrafluoroethylene (PTFE), and B4C nanoparticles was investigated under oil lubrication. The effects of different types of SGF, graphite, PTFE, and B4C nanoparticles on the friction and wear properties of EP were examined using a ball-on-block machine. The worn surfaces were characterized using optical microscopy, SEM-EDX, XPS, and TEM. The anti-wear mechanisms were proposed based on the experimental observations and analysis. The results demonstrate that the addition of SGF significantly reduces wear and friction in the EP matrix. In contrast, the incorporation of B4C nanoparticles and other solid lubricants does not have a significant effect on friction and wear. The remarkable tribological properties observed in the SGF-reinforced EP composites can be attributed to the superior load-bearing capabilities and wear durability of SGF. These fibers effectively withstand the load and exhibit excellent durability during sliding, resulting in reduced wear and friction.
