ABSTRACT:
A wet friction material composition for use in clutches, brakes and the like is composed of a resilient binder comprising a fluoroelastomer. The friction material is characterized by containing a significant amount of wollastonite as a filler, which unexpectedly alters the ratio between the dynamic and static coefficients of friction exhibited by the friction material during actual use.
