摘要/Abstract

摘要： 采用正交试验设计的方法制备得到不同配比的新型高摩合成材料,通过极差分析方法探索了组分对合成材料摩擦系数、弹性模量的影响规律。在MMS-2A摩擦磨损试验机上测试了材料的摩擦系数,用OLS4100型-3D激光共聚焦显微镜观察了摩擦试样的磨损形貌,探索分析了组分影响合成材料摩擦磨损性能的内在机理,并用TG/DTA7300型号热分析仪和SANS试验机对合成材料的热性能及力学性能进行测试,获得组分对各种性能的影响规律。结果表明:高性能填料与丁腈橡胶对材料的摩擦系数影响最大,纤维影响最小;纤维对弹性模量的影响最明显,影响最小的是高性能填料。建立了模型摩擦系数与弹性模量的回归模型,其R²值分别为0.94与0.955。合成材料开始分解的温度在300 ℃左右,材料的耐热性能随着橡胶含量的增加而降低。通过对表面形貌进行分析,发现不同的组分对合成材料磨损机制的影响规律。

Abstract: The high friction composite materials with different proportion were prepared by orthogonal design. The influence of ingredient on the friction coefficient and elastic modulus were studied by range analysis. The friction tests were performed using MMS-2A friction tester. The surface morphology of friction materials were analyzed by 3D Measuring Laser Scanning Microscopy OLS4100 and the discipline of ingredient with material were studied. The thermal weight loss of materials were analyzed by TG/DTA7300 thermal analyzer and mechanical properties were tested by the SANS testing machine. The results show that the major affecting factors affecting friction coefficient is confidential filler and nitrile rubber, while the minor factor is Fiber. Fiber is the main factor affecting the elastic modulus, and confidential filler is the minor factor. Multiple regression analysis of friction coefficient and elastic modulus were built, and R2 are 0.94 and 0.955, respectively. The thermal decomposition temperature of composite materials is about 300℃, and the heat resistance decreased with the increase of the nitrile rubber. The main wear mechanisms were different for different composite materials by the analysis on surface morphology.

Key words: orthogonal test, composition material, tribological properties, thermal weight loss, wear mechanism
