【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。
[Abstract]:In order to overcome the shortcoming of low structural strength of short cut fiber and two dimensional carbon cloth reinforced preform, two kinds of layered and three dimensional woven carbon fiber preforms reinforced phenolic resin matrix composites were designed and fabricated, respectively. The short cut carbon fiber reinforced phenolic resin matrix composites were prepared by the same composite process. The friction properties of carbon fiber / phenolic resin composites were tested, and the wear surfaces and micromorphology of wear debris of the three composites were observed. The friction mechanism is discussed. The results show that the friction coefficient and wear rate of short cut fiber composites are the highest, and the friction coefficient and wear rate of deep crosslinking are the lowest. The preform of three dimensional woven structure with stratified joint has excellent mechanical properties and integrity, which can reduce debris and wear and maintain a stable friction coefficient in the friction process of composite materials. Thus, the composites have good friction properties.
