| 摘要:为优化碳纤维摩擦材料的结构设计并调控其摩擦学行为，本研究采用酚醛树脂溶液分别浸渍碳纸原纸、碳毡和碳布3种聚丙烯腈（PAN）基碳纤维预制体，经热压、固化处理，制得碳纤维摩擦材料，研究了不同预制体结构对其表面微观形貌、孔隙结构、硬度、剪切强度、压缩回弹性能及摩擦磨损性能的影响。结果表明，相比于碳布，碳纸原纸和碳毡所制碳纤维摩擦材料的孔隙率分别增加了386.2%和338.3%，硬度分别降低了34.0%和30.1%；压缩率分别增加了60.0%和24.1%，回弹率分别降低了5.6%和4.6%，永久形变率分别增加了151.7%和101.7%，且二者剪切强度均明显降低。摩擦磨损后，碳纸原纸与碳毡所制碳纤维摩擦材料均表现出较优摩擦性能，中点摩擦系数分别为0.116~0.141和0.105~0.131，端/中点摩擦系数比分别为0.952~1.081和1.082~1.173，磨损率分别为2.16×10-6和1.46×10-6 cm3/J。而对于碳布所制碳纤维摩擦材料，其中点摩擦系数为0.094~0.118，端/中点摩擦系数比为0.987~1.115，磨损率为1.18×10-6 cm3/J，表现出良好的接合稳定性和耐磨耐久性。 |
| Abstract:To optimize the structural design and regulate tribological properties of carbon fiber friction materials， three types of polyacrylonitrile (PAN)-based carbon fiber preforms including raw carbon paper， carbon felt， and carbon cloth were impregnated with phenolic resin solution. Carbon fiber friction materials were subsequently manufactured via hot pressing and curing. The influences of different preform structures on surface micromorphology， pore structure， hardness， shear strength， compression resilience， friction， and wear performance of the materials were investigated. The results revealed that compared with carbon cloth-based samples， the carbon fiber friction materials prepared from raw carbon paper and carbon felt showed porosity increased by 386.2% and 338.3%， hardness declined by 34.0% and 30.1%， compressibility increased by 60.0% and 24.1%， resilience rate declined by 5.6% and 4.6%， and permanent deformation rate increased by 151.7% and 101.7%， respectively， both accompanied by a remarkable reduction in shear strength. After friction and wear tests， raw carbon paper and carbon felt-based fiber friction materials achieved superior friction performance. Their midpoint friction coefficients were 0.116~0.141 and 0.105~0.131， end-to-midpoint friction coefficient ratios were 0.952~1.081 and 1.082~1.173， and wear rates were 2.16×10-6 and 1.46×10-6 cm3/J， correspondingly. By contrast， carbon cloth-based fiber friction material possessed a midpoint friction coefficient of 0.094~0.118， an end-to-midpoint friction coefficient ratio of 0.987~1.115， and a wear rate of 1.18×10-6 cm3/J， which exhibited outstanding bonding stability and long-term wear resistance. |
