Description

technical field

[0001] The present invention relates to a friction member, which is suitable as a material for a brake member, such as a material for a clutch friction plate, that is, a material for a brake, and the like, and is used in brake devices for motor vehicles, aircraft, railway vehicles, and industrial equipment. Background technique

[0002] Conventionally, as a friction material in a brake, asbestos is dispersed and bonded to an organic or inorganic adhesive.

[0003] However, since such friction materials have insufficient friction and wear characteristics such as heat resistance, and asbestos has environmental and sanitation problems such as carcinogenicity, development of substitutes has been urgently required.

[0004] In response to this requirement, a friction member using potassium titanate fiber as a matrix fiber or a friction modifier has been proposed. This kind of friction part has the following excellent features. Potassium titanate fibers are not as...
