摘　　要：为克服短切纤维和二维碳布增强预制体结构强度低的缺点,分别设计并制备了浅交弯联和深交联2种分层接结三维机织碳纤维预制体增强酚醛树脂基复合材料,并以相同复合工艺制备了短切碳纤维增强酚醛树脂基复合材料。测试碳纤维/酚醛树脂复合材料的摩擦性能,并通过观察3种复合材料的磨损表面和磨屑的微观形貌,探讨了其摩擦机制。结果表明:短切纤维复合材料的摩擦因数和磨损率最高,深交联的摩擦因数和磨损率最低,浅交弯联的居中。分层接结三维机织结构预制体具有优良的力学性能和整体性,会使复合材料在摩擦过程中减少磨屑与磨损,保持稳定的摩擦因数,从而使复合材料具有良好的摩擦性能。In order to overcome shortcoming of the shorter fiber and two-dimensional carbon fabric reinforced perform on low structure strength, the paper designed and prepared the deep crossing linking woven and the curved shallow crossing linking woven carbon fabric reinforced phenolic resin composites. And the shorter carbon fiber reinforced phenolic resin composites was prepared under the same conditions as the controlled trial. The friction and wear properties of the carbon fiber/phenolic resin （C/PR） composites were tested and the three kinds of worn surfaces were observed. The results showed that： the friction coefficient and the wear rate of the shorter fiber composite were the highest; the curved shallow crossing linking woven C/PR composite has the lowest friction coefficient and the wear rate; and shallow curved cross-linking is in the middle. The three dimensional woven structure of layered joint has excellent mechanical properties and integrity of the composite material and can reduce wear dust and wear loss of the composite in the friction process, and keeps stable friction coefficient, so that the composite has good frictional properties.
