  • BRAKE FRICTION MATERIAL FOR STAINLESS STEEL DISC
    Publication number: 20170067525
    Abstract: Disclosed is a brake friction material for stainless steel brake discs, as a non-asbestos-based organic friction material not including asbestos. The brake friction material can enhance braking characteristics and wear resistance of a stainless steel brake disc. The brake friction material for stainless steel discs comprises a fiber base, a binder, a filler and a friction modifier. In particular, the friction modifier is included in an amount of about 10 to 22% by volume based on the total volume of the brake friction material composition and comprises zirconium oxide (ZrO2), iron oxide (FeO), graphite (C), tin (Sn) powder and alumina (Al2O3).
