Abstract
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.
