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。
