Method for Extracting Full Spectrum of Friction Materials Performance (Fingerprinting) using the SAE J2681

This paper reports the progress that has been made to date on a research program that has as its focus extracting the full spectrum of friction material performance. In contrast to existing friction test specifications, the new program considers the rise of coefficient of friction at each application by using a statistical evaluation. The statistical evaluation allows also a batch to batch control by monitoring statistical values.
