Abstract
Wear of carbon fiber composites increases with increasing temperature. At temperatures below about 100 C, wear is influenced by the type of carbon fiber and the presence of transfer films on the counterface. Beyond 100 C, transfer films no longer exist and wear becomes independent of the type of fiber. Increasing rates of wear at elevated temperatures are attributed to progressive desorption of water from the carbon fibers. Reduced wear at elevated temperatures may be achieved by incorporation of CdI2 in the composite. However, volatility of this material restricts the temperature capability of composites to approximately 350 C.
