Automotive brake materials usually consist of several ingredients which are classified as fibrous reinforcement, binder, filler and friction modifier. A high quality friction material must possess stable friction and low wear to satisfy the varying and rigorous service conditions. Braking hard or frequently can create a large increase in temperature due to the friction heating produced on the mating surfaces between the brake and brake friction material. The temperature can increase largely and cause the friction material to be less effective than it used to be at low temperature, reducing the brake's efficiency. When an organic friction material is subjected to such high temperatures, the normal low-temperature coefficient of friction decreases and this phenomenon is called 'brake fade' or fade. In this work, a tribological investigation was conducted on a carbon-fiber-reinforced phenolic friction material using a D-MS friction material testing machine. The objective of the work described in this letter was to determine the fade characteristics of the friction materials in the devotes temperature range of 100-300DGC. A phenolic resin is generally chosen as the binder in polymeric brake materials due to its excellent thermal stability. An acrylonitrile-butadiene rubber-modified phenolic (Heilongjiang Chemical Institute, China), was used in this study.
