摘　　要：采用2.5D浅交弯联碳纤维整体织物作为预制体,以酚醛树脂为基体,通过热压成型工艺制备了碳纤维整体织物结构增强树脂基复合材料。通过MST-3001摩擦磨损试验机分别考核了干式与湿式条件下复合材料的摩擦磨损性能;采用扫描电子显微镜(SEM)、3D激光扫描形貌仪观测了材料的表面形貌。结果表明,干式摩擦条件下,动摩擦系数波动范围0.12~0.26,随着转速的增加摩擦系数先降低后升高,随着载荷的增加摩擦系数变化不明显。湿式摩擦条件下,动摩擦系数波动范围0.08~0.13,随着转速和载荷的增加,摩擦系数降低。在连续摩擦状态,干式工况条件下动摩擦系数波动较大,湿式工况条件下动摩擦系数非常平稳。干式摩擦状态时,材料的主要磨损形式为磨粒磨损,而湿式摩擦时主要发生磨粒磨损和疲劳磨损。The phenolic resin composites reinforced by 2.5D woven fabric of carbon fiber were prepared by hot pressing process.Dry tribological properties and wet tribological properties of the material were evaluated by MS-T3001 friction and wear tester.Superficial microstructure of friction material was observed by scanning electron microscope（SEM）and three-dimensional laser microscope.Results show that under the condition of dry friction,friction coefficient decreased firstly and then increased with the increasing of the relative sliding speed but had no significant changes with the increasing of work load.The fluctuation interval of friction coefficient is 0.12-0.26.Under the condition of wet friction,friction coefficient continuously decreased with the increasing of the relative sliding speed and work load.The fluctuation interval of friction coefficient is 0.08-0.13.Friction coefficient and friction temperature had considerable fluctuation under the condition of dry friction and keep stable under the condition of wet friction in continuous friction experiment.Abrasive wear is the main form of wear for dry friction,but in wet friction,whose main wear form is abrasive wear and fatigue wear.
