摘    要:利用MG-200型摩擦磨损试验机研究了炭纤维增强环氧树脂复合材料/N80钢的摩擦学性能,考察了介质温度对摩擦学性能的影响;用扫描电子显微镜分析了磨损表面形貌.结果表明:在干摩擦条件下,炭纤维增强环氧树脂复合材料与N80钢对摩时的摩擦系数较低,炭纤维增强环氧树脂复合材料的磨损主要表现为树脂基体脱落碳化和炭纤维的折断剥落,偶件钢环则呈现明显的磨粒磨损特征;在油井产出液润滑下炭纤维增强环氧树脂复合材料的磨损率较低,摩擦系数和磨损率随着润滑介质温度的升高而增大,偶件钢环则呈现明显的磨粒磨损和腐蚀磨损特征.

关 键 词:炭纤维  环氧树脂复合材料  抽油管  摩擦学性能

Abstract:The friction and wear behaviors of carbon fiber reinforced epoxy resin composites sliding against N80 steel under dry and lubricated conditions were investigated on an MG-200 test rig in a block-on-ring configuration, using the commonly used D-grade steel as a reference. The worn surface morphologies of the composites and the counterpart steel rings were observed on a scanning electron microscope. It was found that the carbon fiber reinforced epoxy resin composites had much better wear resistance and slightly increased friction-reducing abilities than the commonly used D-grade steel. The reinforced epoxy resin composites were characterized by resin matrix peeling off and breakage of the reinforcing carbon fibers as they slid the N80 steel under dry friction, while the counterpart steel was characterized by abrasion. Though the oil-well liquid as the lubricant led to corrosion of the counterpart steel, itgreatly restrained the resin matrix peeling off and hence considerably decreased the wear rate of the composites and the counterpart steel as well. Therefore, the carbon fiber reinforced epoxy resin composites could find promising application in the preparation of oil-sucker rod.
Keywords:carbon fiber  epoxy resin composite  oil-sucker rod  tribological properties
