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.

The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.
