环氧树脂广泛应用于工程应用中。然而，它们的低热稳定性限制了它们在高滑动速度和载荷下的使用。机械零件的机械性能和热稳定性在摩擦磨损过程中是非常重要的。本文研究了多壁碳纳米管（MWCNTs）和氮化硼（BN）改性环氧树脂的摩擦学性能。研究了三种不同的纳米粒子结构（0.3%MWCNT、0.5%BN和0.5%MWCNT/0.3%BN）对环氧树脂的改性。比较了纳米粒子改性环氧树脂与纯环氧树脂的摩擦学性能。使用球盘试验台在10 N施加载荷下以1.2和1.5 ms−1的滑动速度测试改性环氧树脂的摩擦和摩擦学行为。测试是在干燥条件下进行的，距离为1，800米。测试过程中的摩擦系数，磨损量，和温度升高进行了记录，并与纯环氧树脂得到的。据观察，纳米粒子改性导致增强的耐磨性和降低摩擦系数和工作温度。
Epoxy resins are widely used in engineering applications. However, their low thermal stability limits their usage at high sliding velocities and loads. The mechanical properties and thermal stability of a machine element subjected to friction and wear are very important. In this study, friction and tribology behaviors of multiwalled carbon nanotubes (MWCNTs) and boron nitride (BN)-modified epoxy resin have been investigated. Epoxy resin modified by three different nanoparticle configurations, 0.3% MWCNT, 0.5% BN, and 0.5% MWCNT/0.3% BN, was investigated. The tribological characteristics of nanoparticle-modified epoxy resin were compared with properties of neat resin. The friction and tribological behavior of modified epoxy resin were tested using a ball-on-disc test stand at 1.2 and 1.5 ms−1 sliding velocities under 10 N applied load. The tests were done under dry condition and 1,800 m distance. The friction coefficient, wear loss, and temperature increase during testing were recorded and compared with that obtained for neat epoxy. It is observed that nanoparticle modification resulted in enhanced wear resistance and a reduction in friction coefficient and working temperatures.
