Abstract

Our previous study (Polymer Composites 2023, 44: 1252–1263) revealed the positive role of rubber in modifying the tribological properties of polymer composites. This concept was applied here by incorporating synthetic Eucommia rubber (TPI) to 3D printed polyether ether ketone (PEEK) skeletons with different infill densities. The formation of TPI/PEEK composite improved the friction and wear of PEEK matrix with some reduction in mechanical performance. The composite with 70% infill density is recommended in terms of its overall performance. Based on the morphological and chemical analysis, the composite's wear mechanism was discussed. The findings of this present study could pave a new route to modify friction‐reduction and anti‐wear performance of PEEK.Highlights

Novel composites were successfully prepared from thermodynamically incompatible synthetic Eucommia rubber (TPI) and polyether ether ketone (PEEK).

The tribological properties of TPI/PEEK composites were studied in association with the infill density of PEEK.

The TPI rubber helped improve the friction and wear properties of PEEK thanks to its role in enhancing the formation of transfer films on the counter steel surface.

聚醚醚酮/合成杜仲橡胶复合材料的摩擦学特性

我们之前的研究（Polymer Composites 2023, 44: 1252-1263）揭示了橡胶在改变聚合物复合材料摩擦学特性方面的积极作用。在此，我们将合成杜仲橡胶（TPI）应用于具有不同填充密度的三维打印聚醚醚酮（PEEK）骨架。TPI/PEEK复合材料的形成改善了PEEK基体的摩擦和磨损，但机械性能有所下降。就整体性能而言，推荐使用填充密度为 70% 的复合材料。根据形态和化学分析，讨论了复合材料的磨损机理。本研究的结果可为改进 PEEK 的减摩和抗磨损性能铺平一条新的道路。研究了 TPI/PEEK 复合材料的摩擦学特性与 PEEK 填充密度的关系。由于 TPI 橡胶能增强对钢材表面转移膜的形成，因此有助于改善 PEEK 的摩擦和磨损性能。

期刊介绍： For more than 30 years, Polymer Engineering & Science has been one of the most highly regarded journals in the field, serving as a forum for authors of treatises on the cutting edge of polymer science and technology. The importance of PE&S is underscored by the frequent rate at which its articles are cited, especially by other publications - literally thousand of times a year. Engineers, researchers, technicians, and academicians worldwide are looking to PE&S for the valuable information they need. There are special issues compiled by distinguished guest editors. These contain proceedings of symposia on such diverse topics as polyblends, mechanics of plastics and polymer welding.
