Abstract
To provide a method of pelletizing friction material that makes it possible to preliminarily form friction materials after pelletizing, and a method of producing preliminarily formed friction material. The method of pelletizing friction material includes the steps of: pressing powdery friction material without heating, in which plurality of materials are mixed, with 0.1 to 5.0 weight-percent of solvent; and grinding the pressed and hardened material. When handling powdery friction material, in which plurality of materials including at least one sticky material are mixed, less than or equal to 5.0 weight-percent of solvent is added in the pressing process. Feeding the pelletized material in a metal mold and pressing the material without heating produce a preliminarily formed friction material.
