摘    要:为优化矿物纤维增强酚醛树脂基摩擦材料的热压工艺,该文采用均匀试验设计方法对干法共混热压成型工艺对摩擦材料性能(摩擦磨损性能、冲击强度、硬度等)的影响规律进行了研究。得出摩擦材料的热压成型工艺,即热压压力40MPa、热压时间10min、热压温度200℃。用SAS软件对数据进行优化分析,得出了成型压力、保温时间和热压温度对摩擦材料的摩擦因数、冲击强度的回归关系,建立了摩擦因数、冲击强度与热压工艺参数的二次响应曲面回归模型。利用MATLAB软件,分析了热压压力和热压温度的交互作用。结果表明:当温度固定,摩擦因数随压力的升高而下降;当压力固定,摩擦因数随温度的升高而上升。在热压压力50MPa、热压时间40min时,冲击强度达到最大值。该研究可为研制高性能的摩擦材料制品提供技术参考。

Abstract:In order to optimize the hot-press processing of the friction material based on the phenolic resin reinforced with the mineral fiber,the influences of dry-mixing hot-press processing on the properties of the friction material,such as wear property,impact strength and hardness,were researched by using uniform experiments in this paper.The best hot-press processing of the friction material were that hot press was 40 MPa,hot press time was 10 min and hot press temperature was 200℃.The regression relationship of the model pressure,the time of heat preservation,the hot press temperature on the friction coefficient and the impact strength of the friction material were carried out through the optimization using SAS,and then the quadratic curve-surface regression model among the friction coefficient,the impact strength and the parameter of the hot press processing was established.The interaction between hot pressure and hot press temperature was analyzed by using Matlab.The results show that when the temperature was fixed,the friction coefficient decreased with the pressure increasing,and when the pressure was fixed,the friction coefficient increased with the temperature increasing.The impact strength was the largest when hot pressure was 50 MPa and hot press time was 40 min.This study could provide technical reference for the development of high-performance fiction material products.
Keywords:experiments  friction materials  hot pressing  friction coefficient  friction ratio  mineral fiber
