The purpose of the present invention is to provide a friction material that does not contain a copper component or a metal fiber, wherein the friction material has an excellent friction coefficient and wear resistance at a high temperature and a high speed. The present invention pertains to a friction material which contains 7 volume% or more of a biosoluble inorganic fiber and a metal sulfide, and does not contain a copper component or a metal fiber. La présente invention concerne un matériau de friction qui ne contient pas de constituant à base de cuivre ou de fibre métallique, le matériau de friction présentant un excellent coefficient de friction et une excellente résistance à l'usure à haute température et à grande vitesse. La présente invention concerne un matériau de friction qui contient au moins 7 % en volume d'une fibre inorganique biosoluble et un sulfure métallique, et qui ne contient pas de constituant à base de cuivre ou de fibre métallique. 本発明は銅成分及び金属繊維を共に含まない摩擦材であって、高温、高速での摩擦係数及び耐摩耗性に優れた摩擦材を提供することを目的とする。本発明は生体溶解性無機繊維を７体積％以上と、金属硫化物とを含み、かつ銅成分及び金属繊維を共に含有しない摩擦材に関する。
