不锈钢纤维/碳纤维混杂增强聚醚醚酮基摩擦材料的制备与性能
Preparation and Properties of Stainless Steel/Carbon Fiber Reinforced PEEK Friction Material
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、757%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.

Abstract
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.
