(JA) 摩擦材
Abstract: front page image
(EN)Provided is a friction material which is inhibited from decreasing in the coefficient of friction when the brake is to fade at a high temperature under a high load, and which is inhibited from sticking to the disk rotor immediately after a heat history and has improved strength in a high-temperature region. The friction material comprises a fibrous base, a binder, and a friction modifier, the friction modifier comprising an artificial graphite having an average particle diameter of 1,000-3,000 µm and an inorganic filler having a plurality of protrusions.
(FR)L'invention porte sur un matériau de frottement dont le coefficient de frottement est empêché de diminuer lorsque le frein est amené à s'atténuer à une température élevée sous une forte charge, et qui est empêché de coller au rotor de disque immédiatement après un historique de chauffage, et qui a une robustesse améliorée dans une région de haute température. Le matériau de frottement comprend une base fibreuse, un liant, et un agent de modification de frottement, l'agent de modification de frottement comprenant un graphite artificiel ayant diamètre de particules moyen de 1000-3000 µm et une charge minérale ayant une pluralité de saillies.
(JA) 本発明は高温高負荷フェード時の摩擦係数低下を抑制し、且つ熱履歴直後のディスクロータへの貼り付きを抑制し、更に高温域での摩擦材強度を向上させた摩擦材を提供することを目的とする。本発明は、繊維基材、結合材及び摩擦調整材を含む摩擦材であって、該摩擦調整材として、平均粒子径1000~3000μmの人造黒鉛と、複数の凸部を有する無機フィラーとを含む摩擦材に関する。
