The results show that influence of content of kraft fiber on compressure-resilience and tribology properties was inapparent, however the compressure rate and resilient rate were increased when pressure was increased, and friction coefficient was decreased to some extent when pressure and rotate speed were increased.

在相同比压和转速条件下，纸浆纤维含量对纸基摩擦材料动摩擦系数的影响不明显，但随着比压和转速的增加，纸基摩擦材料的摩擦系数降低，其中含有17.5%纸浆纤维的纸基材料在循环制动条件下的摩擦系数最稳定，磨损率最低。

The results show that when the porosity of sample was higher, compressure rate was higher and resilience rate was lower, however resilient rate of sample with higher porosity were increased notably when pressure was increased, and it tended to accord with of sample with lower porosity. The friction coefficient was higher when porosity of paper-based friction material was higher, and the friction coefficient tended to reduce and stabilize when braking pressure was increased. The friction coefficient of sample with high porosity tended to reduce and stabilize in continuous braking cycles.

结果表明：在相同载荷下，随着孔隙率增大，材料的压缩率增加而回弹率降低，随着载荷增加，高孔隙率材料的回弹率先明显增大，而后趋于稳定；在相同比压和转速下，孔隙率越高，材料的摩擦系数越大，随着比压增加，孔隙率高的材料摩擦系数逐渐降低，且不同孔隙率材料的摩擦系数逐渐趋于一致；在连续循环制动时，高孔隙率材料的摩擦系数逐渐降低并趋于稳定。
