Friction material

摘要

A friction material comprises a fibrous reinforcement, a friction modifier and a binder. At least potassium hexatitanate fiber and potassium octatitanate fiber are used together as the fibrous reinforcement and mixed at a ratio in a range between 2 wt % and 40 wt % of the whole of the friction material as total amount. It is preferable that a mixing ratio of the potassium hexatitanate fiber to the potassium octatitanate fiber is in a range between 1:4 and 4:1 by weight percentage.
