提高聚合物基材料的耐磨性可以提高运输机械的能量效率，因为其具有更高的强度重量比。采用球-板摩擦磨损试验机，研究了氧化木用合成铜基颗粒（OWCu）对环氧树脂与钢摩擦副耐磨性的影响。OWCu主要由CuO和少量石墨碳组成，平均粒径约为0.5 μm。与纯环氧树脂相比，OWCu掺入的环氧树脂在大于0.6质量%时观察到更高的耐磨性。讨论了提高耐磨性能的机理，结果表明，OWCu加入环氧树脂后，钢的表面粗糙度保持在较低的水平，这对降低OWCu加入环氧树脂的磨损起着主导作用。OWCu的抛光作用可以降低摩擦过程中钢对件的表面粗糙度。此外，在高于5.0质量%的较高浓度下，OWCu粘附到钢表面，这降低了钢表面的磨损。OWCu是一种很有前途的材料，可以提高聚合物基材料的耐磨性，特别是在低伸长率的情况下。
Improving the wear resistance of polymer-based materials can lead to high energy efficiency of transport machineries owing to the higher strength-to-weight ratio. Oxidized wood-utilized synthesized copper-based particles (OWCu) was incorporated into epoxy resin to investigate its effect on the wear resistance of OWCu-incorporated epoxy with the steel counterpart using a ball-on-plate tribometer. OWCu was mainly composed of CuO with a small amount of graphitic carbon, and the average particle size was approximately 0.5 μm. A higher wear resistance was observed for the OWCu-incorporated epoxy at more than 0.6 mass% compared to the neat epoxy. The mechanism for the improvement of the wear resistance property was discussed, and it was revealed that the surface roughness of the steel counterpart was maintained at a low level for the OWCu-incorporated epoxy, which played a dominant role in reducing the wear of the OWCu-incorporated epoxy. The polishing effect of OWCu could reduce the surface roughness of the steel counterpart in the friction process. In addition, at higher concentrations of more than 5.0 mass%, OWCu adhered to the steel surface, which decreased the wear of the steel surface. OWCu is a promising material to enhance the wear resistance of polymer-based materials, especially with low elongation.
