れている。This semi-metallic friction material is mainly composed of steel fibers and graphite, with a binder such as phenolic resin and fillers such as iron powder and barium sulfate, but friction materials made of semi-metallic material alone have high thermal conductivity. Therefore, a two-layer material structure using asbestos is required as a measure against brake fluid temperature.

A friction material comprising aramid pulp and aramid pulp in a ratio of 100:5 to 30 in a total amount of 10 to 25% by weight, 5 to 20% by weight of a lubricant such as graphite or molybdenum disulfide, and the remainder a binder and filler. The main point is the material.

とができる。According to the present invention, the optimum mixing ratio of metal fibers and/or metal powder and aramid fibers and/or aramid pulp (100:5 to 30) is set, and the total amount thereof is 10 to 25% by weight in the friction material formulation. This makes it possible to use 5 to 20% by weight of a lubricant such as graphite, and as a result, low thermal conductivity is achieved, eliminating the need for special brake fluid temperature measures, and improving the temperature characteristics of the friction coefficient. Furthermore, noise resistance can also be improved by incorporating a fluorine-based organic substance.
