ABSTRACT:
A paper based frictional material is formed by forming a paper material of a desired size from a mixture comprising wood pulp, a lubricant and an organic fiber; soaking said paper material in a binder agent, and then drying the soaked material; and heating said dried paper product to carbonize the same under conditions in which oxygen is substantially eliminated from contact with said paper material so that a material is obtained whose frictional characteristics are such that the material is useful as a clutch facing in automatic transmissions.
