ABSTRACT:
A vehicle component such as a transmission blocker ring (81) having an improved friction material (56) is provided. Friction material (56) comprises a composite of from about 25% to about 75% by weight of a flurocarbon polymer and from about 75% to about 25% by weight of substantially uniformly dispersed ceramic fiber and which is provided with controlled crystallinity by reason of having been cooled at a rate of less than about 20.degree. C. per minute after having been sintered at a predetermined sintering or annealing temperature and time for the friction material.
