FRICTION MATERIAL COMPOSITION, FRICTION MATERIAL USING THE SAME, AND FRICTION MEMBER

摘要

Provided is a friction material composition comprising: a binder; a fibrous base material; an abrasive material; an inorganic filler; and an organic filler,
wherein the friction material composition further comprises:at least one selected from the group consisting of zinc, a cellulose fiber as the fibrous base materials and a flame retardant fiber as the fibrous base materials;an iron-based fiber as the fibrous base material in an specified amount; andan inorganic abrasive material having a Mohs hardness of 8 or higher and a particle size of 1 μm or larger as the abrasive material in an amount of 1 wt % or less. The present invention can provide a friction material composition which is less destructive to facing materials compared to conventional products, which has a high friction coefficient upon braking when used in repeated braking during high-speed traveling, and which is capable of suppressing pad wear and uneven pad wear, in the case that the friction material composition is formed into a brake pad for passenger cars. The present invention can also provide a friction material and a friction member using this friction material composition.
