A friction member of the resin mold type comprising brass fiber of 1-10 mm length having a trapezoid in cross figure thereof as a base material of the friction member, and a phenolic resin of cement composition, to obtain excellent qualities such as good durability at high temperature.

Friction member of resin mold type

Friction facings comprising a non-woven fibrous lamina reinforced with stitching, and impregnated with a curable binder have improved resistance to delamination.

Friction facings reinforced with stitching

A friction member is a clutch facing, a brake pad, or a brake lining which comprises a phenolic fiber, a plated organic fiber, and/or mixed fiber thereof, which may or may not comprise the other fibers such as nonorganic fibers, as based material of the aforementioned friction member, wherein various difficulties of asbestos are improved.

Friction member of non-asbestos

A method of manufacturing a clutch facing including the steps of mixing graphite and phenolic resin to form a graphite mixture, soaking an asbestos fiber string within the mixture, removing the soaked string such that phenolic resin content of between 14-24 weight percents and graphite content of between 1-8 weight percents for every 100 weight percents is produced and bonding the string to the clutch facing such that the Rockwell hardness of the clutch facing is between 20-60 on the Moh scale.

An improvement is disclosed in the dry method for manufacturing friction materials of the resin mold type, especially brake lining pads, which comprises uniformly mixing graphite particles and a phenolic resin in a liquid form, solidifying the mixture, grinding the solidified mixture, and using the ground material as a binder in forming a friction member of the resin mold type. The binder has a graphite powder content of 2-31 wt.% and a phenolic resin content of 69-98 wt.%. Brake linings of improved wear resistance and fade resistance can be produced using this improved method.
