Results show that the equivalent mass in normal direction depends on the modes of collision. In the case of reversed sliding and sticking, the coefficient of restitution varies as a result of the instantaneously changes of the equivalent mass during impacting process. The coefficient of restitution depends not only on the contact force, but also on the kinematical and dynamic parameters of the two rigid bodies. Moreover, a formula is proposed to calculate the coefficient of restitution.

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.
