研究了碳纤维增强聚醚醚酮(CF/PEEK)复合材料的摩擦磨损行为.结果表明复合材料的摩擦系数与磨损率依赖于材料中纤维的含量,在10%~20%范围有最低值,并对载荷有明显的依赖性.纤维含量的影响是碳纤维本身的减摩阻磨性和其对纤维在树脂中所处的分散状态及纤维在作用中的变化的依赖性有关;而载荷的影响则与树脂在作用过程中产生热后所处的物理状态有关.由于纤维对材料的摩擦尤其是磨损性能可能产生不利的影响,如纤维受磨减薄后产生的碎片导致磨料性磨损,而这种影响可通过复合材料的制备工艺来达到一定程度的控制,制备工艺对获得理想材料至关重要
The friction and wear behavior of carbon fiber reinforced polyetheretherketone (CF / PEEK) composites were investigated. The results show that the friction coefficient and the wear rate of the composites depend on the content of the fiber in the material, with the lowest value in the range of 10% ~ 20% and obvious dependence on the load. The influence of the fiber content is related to the friction and wear resistance of the carbon fiber itself and its dependence on the dispersion state of the fiber in the resin and the change of the fiber in the role; and the influence of the load is related to the heat generated during the action of the resin After the physical state of the relevant. Fibers may adversely affect the friction and, in particular, the wear properties of the material, such as the abrasion of the resulting fragments after abrasion reduction of the fibers, which can be controlled to some extent by the preparation of the composite material, The process is crucial to obtaining the ideal material
