聚醚醚酮(PEEK)作为一种高性能特种工程塑料,具有优异的机械性能、耐热性及化学稳定性,在摩擦学领域展现出广阔的应用前景。然而,纯PEEK在高速、高载荷等苛刻工况下耐磨性较差,因而限制了其进一步应用。综述了PEEK复合材料耐磨改性研究进展,重点分析了填充改性、聚合物共混改性以及多元填料协同改性的作用机理与材料性能,并总结了不同改性方法的特点,以期为开发具有优异综合性能与特定功能导向的PEEK复合材料提供理论依据与技术参考。
Polyetheretherketone (PEEK),as a high-performance specialty engineering plastic,exhibits outstanding mechanical properties,thermal resistance,and chemical stability,demonstrating broad application prospects in the field of tribology.However,pure PEEK suffers from poor wear resistance under demanding conditions such as high speeds and heavy loads,thereby limiting its further application.This review summarized the research progress in wear resistance modification of PEEK composites,focusing on the mechanisms and material properties of filler modification,polymer blending modification,and multi-filler synergistic modification.The characteristics of different modification methods were also summarized,aiming to provide a theoretical basis and technical references for developing PEEK composites with excellent comprehensive properties and specific functional orientations.
