中文摘要：
基于本实验室制备的一种炭纤维增强纸基摩擦材料,研究了固化压力对材料孔隙率,动摩擦系数,静动摩擦系数之比,摩擦力矩曲线的影响。研究结果表明：孔隙率随固化压力增加而下降;动摩擦系数随制动压力的增加均呈下降趋势;静动摩擦系数比值随制动压力的增加分布趋势较为复杂：较低的固化压力条件下,静动摩擦系数之比略有上升,而较高的固化压力条件下静动摩擦系数之比则略有下降趋势;摩擦力矩曲线随固化压力升高有轻微翘曲出现。综合考虑固化压力对动摩擦系数、静动摩擦系数比值以及摩擦力矩曲线的影响,在这种纸基摩擦材料成分不变的条件下,其对应较为合适的固化压力约为3.4 MPa。
英文摘要：
Based on the carbon fiber reinforced paper type friction material prepared by our laboratory, the influences of curing pressure on the friction materials, including porosity, dynamic friction coefficient, static/dynamic friction coefficient ratio and friction torque, were studied. The results show that the porosities of samples decrease with the increasing curing pressure; dynamic friction coefficients of samples decrease at different curing pressures with increasing the braking pressure, while the influence on the static/dynamic coefficient ratios is somewhat complex： with increasing the braking pressure, the static/dynamic coefficient ratios of the samples cured at relatively lower pressures tend to rise slightly, as the static/dynamic coefficient ratios of the samples cured at higher pressures tend to decline; there arises a slight cock at the end of the friction torques gradually. 3.4 MPa is the proper curing pressure for the carbon fiber reinforced paper based friction material with fixed component, taking all of the influences shown above into account.
