    • 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; and an 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.
    • 提供了一种摩擦材料组合物,其包含:粘合剂; 纤维基材; 磨料; 无机填料; 和有机填料,其中所述摩擦材料组合物还包含:选自锌,作为纤维基材的纤维素纤维和作为纤维基材的阻燃纤维的至少一种; 铁基纤维作为特定量的纤维基材; 以及Mohs硬度为8以上,粒径为1μm以上的无机研磨材料为1重量%以下的研磨材料。 本发明可以提供一种摩擦材料组合物,与传统产品相比,其在面对材料方面的破坏性较差,在常规产品中,当在高速行驶中用于重复制动时制动时具有高的摩擦系数,并且能够抑制垫磨损和不均匀 在摩擦材料组合物形成乘用车用刹车片的情况下,垫磨损。 本发明还可以提供使用该摩擦材料组合物的摩擦材料和摩擦构件。
