Beschreibung
Zusammenfassung:	To provide a friction material suitable for mass production through injection molding, which exhibits stable and good frictional properties at both a room temperature and higher temperatures beyond 120°C, while offering good wear resistance at higher temperatures beyond 120°C, and a servo motor equipped with a braking device including the friction material.SOLUTION: A friction material comprises an injection-molded article. The friction material comprises 40-55 vol.% of a phenolic resin, inorganic fibers with Mohs hardness of 5 or more, and an inorganic filler with the Mohs hardness of less than 5. The inorganic filler comprises tetrapod crystals.SELECTED DRAWING: None 【課題】射出成形による量産が可能であり、常温でも１２０℃程度より高温の領域においても安定した良好な摩擦特性を有し、かつ、１２０℃程度より高温の領域において良好な耐摩耗性を有する摩擦材及び当該摩擦材を用いた制動装置を備えるサーボモーターを提供すること。【解決手段】射出成形物からなる摩擦材であって、フェノール樹脂４０～５５体積％、モース硬度５以上の無機繊維、モース硬度５未満の無機充填剤を含み、前記無機充填剤がテトラポッド型結晶体を含む、摩擦材。【選択図】なし
