FRICTION OF POLYMERIC BRAKE MATERIALS

P.T.F.E. (Teflon) in brake material formulations produces a positive slope of coefficient of friction versus speed, on a Chase dynamometer. This sliding speed dependence is different from temperature dependence of friction. Teflon added to the brake formulation produces a more tenacious and even film on the metal counter surface with apparent rheopectic behavior.
