Abstract

Nanocomposite made by blending nano-montmorillonite (MMT) and Silicon Rubber (SR) for mechanical and tribological performance is explored in this work. Different configurations of MMT/SR nanocomposite, with 0, 0.5, 2 and 5 wt % of MMT are manufactured by two roll mixing methods. Noticeable improvement in the mechanical and tribological performance is observed, which is also justified by a morphological study of fractured and wear surfaces through SEM. Two percent of MMT loading is found to be the optimum content that shows excellent performance compared to other compositions. The performance improvement can be linked to the good interfacial interaction between the MMT and SR. Statistical modeling through ANOVA is carried out for tribological performance, which reveals the influence of load on the coefficient of friction (COF) and the influence of sliding distance on the wear rate.

摘要

本研究探索了通过混合纳米蒙脱石（MMT）和硅橡胶（SR）制备的纳米复合材料的力学和摩擦学性能。采用双辊混合法制备了MMT含量分别为0、0.5、2和5 wt%的不同结构的MMT/SR纳米复合材料。观察到力学和摩擦学性能有显著改善，通过扫描电子显微镜（SEM）对断裂和磨损表面进行形态学研究也证实了这一点。发现2%的MMT负载量是最佳含量，与其他成分相比表现出优异的性能。性能的提高可归因于MMT和SR之间良好的界面相互作用。通过方差分析（ANOVA）进行统计建模以研究摩擦学性能，结果揭示了载荷对摩擦系数（COF）的影响以及滑动距离对磨损率的影响。
