Abstract
The present invention relates to a fibrous base material comprising fibrillated aramid fibers, cellulose fibers, and at least one type of filler material and a non-asbestos friction material produced therefrom by impregnating the fibrous base material with a phenolic or modified phenolic resin. The friction material exhibits good anti-shuddering properties and is especially useful in continuous slip clutch applications.
