Fabric composites are widely applied as self-lubricating liner for radial spherical plain bearings owing to their excellent mechanical and tribological properties. Nevertheless, the poor interfacial strength between fibers and the resin matrix limits the performance of composites utilized as tribo-materials. To overcome this drawback, a mild layer-by-layer (LbL) self-assembly method was successfully used to construct hybrid fabric composites in the present work. In addition, this investigation addressed the effect of self-assembly cycles on the friction and wear behaviors of hybrid fabric composites under dry sliding condition. The results demonstrate that fabric composites with three or more self-assembly cycles have significantly enhanced surface activities and anti-wear performances. The results obtained in this work can provide guidance in the preparation of selflubricating liner composites and highlight how the LbL self-assembly techniques could influence the properties of hybrid fabric composites.

摩擦学领域应用的层-层自组装方法制备PTFE / Nomex织物/酚醛复合材料

织物复合材料因其优异的机械和摩擦性能而被广泛用作径向球面滑动轴承的自润滑衬里。然而，纤维与树脂基体之间不良的界面强度限制了用作摩擦材料的复合材料的性能。为了克服这个缺点，在本工作中成功地使用了温和的逐层（LbL）自组装方法来构建杂化织物复合材料。此外，这项研究还探讨了自组装循环对干式滑动条件下混合织物复合材料摩擦和磨损行为的影响。结果表明具有三个或更多自组装循环的织物复合材料具有显着增强的表面活性和抗磨性能。
