ABSTRACT:
A process for producing an organic friction article from a composition of materials in a dust free environment. Water is mixed with the composition of organic materials to produce a slurry. A fixed volume of the slurry is communicated into a first mold. The slurry in the first mold is compressed to remove up to 95% by weight of the water to form a briquette. The briquette is conveyed to a force air oven or dielectric heater where the water is further reduced to about 1% of the weight of the briquette. This dry briquette is then placed in a second mold and pressed into the shape of a friction pad. The pressed friction pad is placed in an oven and heated to cure the resin in the composition of materials to complete the manufacture of the organic friction pad.
