Polymer-textile liner composites have potential applications in aerospace applications for reducing the abrasion damage of moving parts during operation owing to their self-lubrication, light weight, and high loading capacity. Herein, Au nanoparticles (AuNPs) are successfully loaded into the lumen of halloysite nanotubes (HNTs) to construct an HNTs-Au peasecod core-shell nanosystem to optimize the wear resistance of phenolic resin-based poly(p-phenylene benzobisoxazole) (PBO)/polytetrafluoroethylene (PTFE) textile composites. Transmission electron microscope (TEM) characterization reveals that the AuNPs are well-dispersed inside the HNTs, with an average diameter of 6–9 nm. The anti-wear performance of the HNTs and Au-reinforced PBO/PTFE composites is evaluated using a pin-on-disk friction tester at 100 MPa. Evidently, the addition of HNTs-Au induces a 27.9% decrease in the wear rate of the composites. Possible anti-wear mechanisms are proposed based on the analyzed results of the worn surface morphology and the cross-section of the tribofilm obtained by focused ion beam transmission electron microscopy.

高分子织物衬里复合材料由于其自润滑、重量轻和高承载能力，在航空航天领域具有潜在的应用前景，可减少运动部件在运行过程中的磨损。在此，金纳米粒子（AuNPs）成功负载到埃洛石纳米管（HNTs）的内腔中，构建了HNTs-Au豌豆核壳纳米系统，以优化酚醛树脂基聚（对亚苯基苯并二恶唑）（PBO）的耐磨性/聚四氟乙烯（PTFE）纺织复合材料。透射电子显微镜 (TEM) 表征表明，AuNPs 在 HNT 内部良好分散，平均直径为 6-9 nm。HNT 和 Au 增强 PBO/PTFE 复合材料的抗磨损性能使用销盘式摩擦测试仪在 100 MPa 下进行评估。显然，HNTs-Au的添加使复合材料的磨损率降低了27.9%。根据聚焦离子束透射电子显微镜获得的磨损表面形貌和摩擦膜横截面的分析结果，提出了可能的抗磨损机制。
