摘要: 为了研究磨削碳纤维复合材料(CFRPs)时,纳米二硫化钼(MoS2)含量对纳米微量润滑效果的影响,制备了不同质量分数(0%,3%,6%,9%,12%)的纳米MoS2和棕榈油混合液,作为纳米微量润滑油液,对碳纤维复合材料进行磨削加工.使用光学显微镜,观测分析碳纤维复合材料的表面粗糙度、表面形貌.使用测力仪对磨削力进行测量,并通过磨削力计算出磨削力比.最后对纳米(MoS2)在纳米微量润滑磨削过程中的作用机理进行了阐述.结果表明,当纳米(MoS2)质量分数为9%时磨削力比最低,为0.0632,表面粗糙度Ra值最小,为1.86μm,且表面碳纤维损伤最小.

Abstract: To investigate the effect of nano MoS2 concentration on minimum quantity lubrication(MQL)in grinding carbon fiber reinforced plastics(CFRPs), the grinding experiments of CFRPs were carried out with lubricating oils of various concentrations(0%, 3%, 6%, 9%, and 12%)of nano MoS2 in palm oil. The surface roughness and morphology of the CFRPs were studied by optical microscopy. The grinding forces were measured by dynamometer, and the grinding force ratio was calculated and analyzed. Also, the CFRPs grinding mechanism with MQL of various nano MoS2 concentrations was explained. The results show that when the mass fraction of nano MoS2 reaches 9%, the grinding force ratio reaches the lowest value of 0.0632, and the quality of surface roughness with Raof 1.86μm and surface morphology of CFRPs are both better than those with other concentrations.

Key words: CFRPs, nano MoS2, MQL grinding, grinding force, surface roughness, surface morphology
