INFLUENCE OF INGREDIENT OF HIGH FRICTION COEFFICIENT COMPOSITE MATERIAL ON THE TRIBOLOGICAL PERFORMANCE

Abstract

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
