The ultrahigh‐molecular‐weight polyethylene (UHMWPE) has become the most widely used material for water‐lubricated bearings. In the research, the effects of introducing sisal fiber (SF) filler materials on the friction and wear characteristics of UHMWPE‐based composites were investigated. The composites were tested against the QSn7‐0.2 copper disc, under water‐lubricated conditions, using a specially designed testing apparatus. The purpose was to identify an improved material which could be used in water‐lubricated bearings. Four types of composites were tested under different sliding velocities and applied loads, which included pure UHMWPE and 10, 20, and 30 wt% SF reinforced UHMWPE. The friction coefficient and wear amount were measured to characterize the tribological properties of these composite materials. Moreover, in order to reveal the primary mechanism involved in friction and wear, various surface characterization techniques were adopted on the surface of composite materials. The analysis results showed that the addition of SF can stabilize the frictional properties and increase the water absorption of SF/UHMWPE composites. Furthermore, the use of a proper percentage of SF can discharge the wear debris, improve the loading capacity, and reduce adhesion wear. The adding of 10% SF in UHMWPE had produced the best anti‐friction properties at low speed and heavy load. This work can serve as a reference for the design of hydrophilic fiber reinforced polymer composites to reduce wear and improve lubrication performance.

剑麻纤维增强超高分子量聚乙烯材料的水润滑特性研究

超高分子量聚乙烯(UHMWPE)已成为水润滑轴承使用最广泛的材料。在研究中,研究了引入剑麻纤维(SF)填料对UHMWPE基复合材料的摩擦和磨损特性的影响。使用专门设计的测试设备,在水润滑条件下,针对QSn7-0.2铜盘对复合材料进行了测试。目的是确定一种可用于水润滑轴承的改进材料。在不同的滑动速度和施加的载荷下测试了四种类型的复合材料,其中包括纯UHMWPE和10、20和30 wt%的SF增强UHMWPE。测量摩擦系数和磨损量以表征这些复合材料的摩擦学性能。此外,为了揭示涉及摩擦和磨损的主要机理,在复合材料的表面上采用了各种表面表征技术。分析结果表明,SF的加入可以稳定SF / UHMWPE复合材料的摩擦性能,提高吸水率。此外,使用适当百分比的SF可以排出磨损碎屑,提高负载能力并减少粘附磨损。在超高分子量聚乙烯中添加10%的SF在低速和重载下产生了最佳的减摩性能。这项工作可作为设计亲水纤维增强聚合物复合材料以减少磨损和改善润滑性能的参考。分析结果表明,SF的加入可以稳定SF / UHMWPE复合材料的摩擦性能,提高吸水率。此外,使用适当百分比的SF可以排出磨损碎屑,提高负载能力并减少粘附磨损。在超高分子量聚乙烯中添加10%的SF在低速和重载下产生了最佳的减摩性能。这项工作可作为设计亲水纤维增强聚合物复合材料以减少磨损和改善润滑性能的参考。分析结果表明,SF的加入可以稳定SF / UHMWPE复合材料的摩擦性能,提高吸水率。此外,使用适当百分比的SF可以排出磨损碎屑,提高负载能力并减少粘附磨损。在超高分子量聚乙烯中添加10%的SF在低速和重载下产生了最佳的减摩性能。这项工作可作为设计亲水纤维增强聚合物复合材料以减少磨损和改善润滑性能的参考。在超高分子量聚乙烯中添加10%的SF在低速和重载下产生了最佳的减摩性能。这项工作可作为设计亲水纤维增强聚合物复合材料以减少磨损和改善润滑性能的参考。在超高分子量聚乙烯中添加10%的SF在低速和重载下产生了最佳的减摩性能。这项工作可作为设计亲水纤维增强聚合物复合材料以减少磨损和改善润滑性能的参考。
