玄武岩纤维和钢纤维含量对树脂基摩擦材料性能的影响研究摘要：玄武岩纤维由苏联于1960—1970年开始研制生产，主要应用于航空航天及军工领域。
玄武岩纤维同碳纤维、芳纶和超高分子量聚乙烯并称为四大高技术纤维，其生产过程中无污染，作为天然矿石制成的纤维，使用后可自然降解，是一种高性能绿色纤维。
玄武岩纤维具有优良的力学性能，其拉伸强力大于E玻璃纤维，而且价格相对较低，应用前景十分广阔。
此外，玄武岩纤维熔点高、耐腐蚀性较好，还具有优良的减震性，可广泛应用于高温隔热、化学过滤、建筑、隔音等领域。
通过对钢纤维的使用能较大程度的提升混凝土的强度，相当于普通混凝土技术的好几倍，还能提高抗拉能力。
与普通的混凝土技术比较来看，钢纤维混凝土技术的强度更高一些，所以才有更佳的冲击性能。
基于此，本篇文章对玄武岩纤维和钢纤维含量对树脂基摩擦材料性能的影响进行研究，以供参考。

1玄武岩纤维表面结构及成分玄武岩纤维是由天然的、耐多种酸腐蚀的二氧化硅及其它氧化物组成的,经高温熔融拉制成的无机连续纤维。
纤维外表光滑,有金属光泽,以层状结构单元为主,链状结构单元和岛状结构单元为辅,属“类平面结构”。
地球熔岩形成的玄武岩纤维,含多种化学成分,不同矿床,化学成分含量变化大,同时玄武岩纤维的性能受化学成分含量的影响。
玄武岩纤维中含量最高也是最主要的成分是SiO,其次2是Al2O3,而后是含铁氧化物(FeO、Fe2O3)等。
其中二氧化硅和氧化铝的含量是影响纤维的机械性能和化学稳定性,含铁氧化物是影响纤维的导热性能和使用温度,氧化钙、氧化镁的含量影响纤维的耐腐蚀性和化学稳定性,而二氧化钛的含量对熔化材料制备细纤维有影响。
钢纤维含量对汽车摩擦材料性能的影响刘伯威;张小英;杨阳【摘要】By changing the content of steel fiber based on the basic formula, the friction materials with different composite were prepared by directly mixed process. The physical and chemical properties, mechanical properties, tribological properties and brake noise test were completed. The results show that, when steel fiber content increases, the density of the friction material, pH and Rockwell hardness increase; however, the compressibility reduces at room temperature; the porosity firstly decreases and then increases when the steel fiber content is over 21%;μnom slightly decreases and then increases;μmin, the amount of wear and the incidence of noise all increases, but when the steel fiber content is over 21%, the amount of wear and the incidence of noise significantly increase.%通过调整摩擦材料基础配方中钢纤维的含量，采用直接混合工艺制备不同组分的摩擦材料，对其进行理化性能、力学性能、摩擦性能及制动噪音测试。

方法用硅烷偶联剂（KH550）对纳米Mullite表面进行修饰，分别制备质量分数为0.03%的纳米Mullite和KH-mullite的聚脲润滑脂。
采用四球摩擦试验机测试纳米Mullite和KH-mullite作为添加剂对聚脲润滑脂摩擦学性能的影响，利用扫描电子显微镜（SEM）和三维表面形貌仪观察磨损表面形貌，通过X射线能量色散能谱仪（EDS）分析磨损表面的元素分布，使用X射线光电子能谱（XPS）分析磨损表面润滑膜的元素价态，探究添加剂在聚脲润滑脂中的作用机理。
结果经过修饰后，纳米KH-mullite在聚脲润滑脂中的减摩抗磨性能较优，摩擦因数和磨斑直径分别降低了22.4%、15.6%。
通过SEM和三维表面轮廓仪观察磨损表面发现，KH-mullite添加剂能够有效降低磨损表面的粗糙度，修复磨损表面。
KH-mullite聚脲润滑脂优良的摩擦学性能归功于两点，首先KH-mullite能够沉积并吸附在磨损表面，在起到修复作用的同时促进了润滑膜的形成；其次，KH-mullite能够进入润滑膜中，将摩擦副之间的摩擦方式变为滚动摩擦。
结论Mullite和KH-mullite都具有提升聚脲润滑脂润滑性能的作用，经硅烷偶联剂修饰后的KH-mullite在减摩抗磨性能方面表现更优越。

The currently used method is to modify the surface of nanoparticles to improve their dispersibility. Therefore, this study chose to investigate the effect of KH550-modified mullite (Al2O3-SiO2 system) on the frictional properties of polyurea lubricating grease.In this study, the silica coupling agent (KH550) was used to modify the surface of nano-mullite, and polyurea lubricating grease containing 0.03% nano-mullite and KH-mullite were prepared, respectively. The frictional properties of polyurea lubricating grease with nano-mullite and KH-mullite as additives were evaluated with a four-ball friction tester (MRS-10D).GCr15 steel balls were used as the friction pairs in the test, and a composite grease with a mass of 10 g was used each time. The test duration was 60 minutes. The surface morphology of the worn surface was observed with a scanning electron microscope (SEM) and a three-dimensional surface profiler. Energy-dispersive X-ray spectroscopy (EDS) was used to analyze the element content of the worn surface and X-ray photoelectron spectroscopy (XPS) was used to analyze the valence states of the elements in the lubricating film on the worn surface to explore the mechanism of mullite and KH-mullite in polyurea lubricating grease.The results showed that mullite, as an additive, could effectively improve the frictional properties of polyurea lubricating grease. Compared with that before modification, the nano-KH-mullite after modification showed better anti-wear and friction-reducing properties in polyurea lubricating grease, with a decrease in friction coefficient and wear scar diameter of22.4% and 15.6%, respectively. Observations were made on the worn surface using SEM and a 3D surface profilometer, and itwas found that after the addition of molybdenum disulfide lubricant, there were few wide and deep furrows on the worn surface, indicating the presence of abrasive wear. In contrast, the wear surface lubricated with KH-mullite was smoother, and the surface roughness was improved, indicating the presence of polished wear.EDS analysis revealed that, compared with the worn surface lubricated with mullite, the worn surface lubricated with KH-mullite had an increased oxygen element content, indicating that KH-mullite could deposit a large amount on the frictional surface to provide a friction repair effect. XPS element analysis showed that KH-mullite had good compatibility with polyurea lubricating grease, and could carry the stress between the friction pairs in the lubricating film while moving along the surface, transforming the sliding friction into rolling friction and thereby improving the frictional performance of the polyurea lubricating grease. Therefore, it can be concluded that both mullite and KH-mullite can improve the lubricating performance of polyurea grease, but KH-mullite modified with silane coupling agent exhibits superior anti-friction and anti-wear properties.KEY WORDS: mullite; nano-additives; KH550; polyurea grease; tribological properties; wear mechanism摩擦磨损广泛存在于自然界中，它会降低能源的有效利用率[1-2]。
