摘　　要：研究了不锈钢纤维／碳纤维混杂增强聚醚醚酮(PEEK)树脂基半金属摩擦材料的配比、成型工艺对其摩擦磨损性能的影响,对其摩擦磨损机理进行了初步分析。结果表明:制备摩擦材料的优化工艺条件是热压温度320℃、压力35 MPa、保温时间3 min／mm,固化处理工艺为80℃×30 min+150℃×30 min+270℃×30 min+320℃×180 min;最佳配方为19．63％的PEEK、7．57％的不锈钢纤维、10．97％的碳纤维、6．51％的腰果壳油粉及55．33％的填料。经优化工艺制备的摩擦材料的摩擦因数稳定,磨损率低,摩擦材料的磨损在低温区主要属于磨粒磨损,在较高温度时属于粘着磨损和磨粒磨损的共同作用。The mixture ratio of a semi-metallic stainless steel/carbon fiber reinforced polyetheretherketon （PEEK）-based friction material and the influence of molding process on abrasion performance were studied. The abrasion mechanism was analyzed. The process of preparing friction material was molding at 320℃ and pressure 35 MPa for 3 min/mm, then post-curing at 80℃×30 min＋150℃×30 min＋270℃×30 min＋320℃×180 min. The best formulation is PEEK 19. 63%, stainless steel fiber 7. 57%, carbon fiber 10. 97%, cashew 6. 51% and fillers 55. 33%. The developed material has steady friction coefficient and low abrasion value. The wear mechanism is particle abrasion at low temperature but adherence abrasion as well as particle abrasion at higher temperature.
