Carbon Reinforced Composite Bearing Structures.

Abstract

Thrust bearing tests have shown carbon/ graphite fiber compactions to operate satisfactorily as self lubricated bearings wearing against mild steel for pressures up to 1000 psi and sliding velocities up to 300 fpm. The wear rates of the graphite fibers decrease as the fiber modulus increases. Only one type of carbon fiber was tested and it showed lower wear rates than any of the graphites. It was found that the wear rates of the high fiber volume fraction (50%) COMPOSITES WERE CONTROLLED BY THE FIBER PROPERTIES. The matrices had little effect on the wear rate but generally reduced the coefficient of friction slightly. High temperature organic matrices tested include polyimides and both graphitized and carbonized phenolics. (Author, modified-PL)
