Friction material and corresponding disc brake pad

The present invention relates to a friction material, a pad for a corresponding disc brake and a brake system comprising said pad, in which the so-called "creep noise" phenomenon is suppressed or significantly reduced. More specifically, the present invention relates to a graphite-free friction material comprising: from 20% to 30% by volume of one or more abrasives; from 10% to 20% by volume of coke; up to 10% by volume of one or more metal sulfides; up to 20% by volume of one or more metals, and/or metal alloys, and/or intermetallic compounds in powder form; up to 40% by volume of a fibrous material comprising aramid fibers and steel fibers; 10% to 20% by volume of a phenolic resin as a binder; up to 10% by volume of one or more fillers selected from the group consisting of calcium hydroxide, friction powder, PTFE and fluorite. 本发明涉及一种摩擦材、对应的盘式制动器的衬垫和包括所述衬垫的制动系统，其中，所谓的"蠕动噪声"现象被抑制或被显著减轻。更具体而言，本发明涉及一种不含石墨的摩擦材料，该摩擦材料包括：按体积计20％至30％的一种或更多种磨料；按体积计10％至20％的焦炭；按体积计达10％的一种或更多种金属硫化物；按体积计达20％的呈粉末形式的一种或更多种金属、和/或金属合金、和/或金
