ABSTRACT:
A bearing, seal or brake material is disclosed comprising a graphite fiber reinforced glass matrix material. The bearings, seals and brakes according to the present invention have a coefficient of friction of about 0.15 to about 0.7 and a steady state wear rate less than 40.times.10.sup.-10 cm/cm. The advantage of such bearings, seals and brakes are stability at higher operating temperatures, low reactivity to chemical and other severe environments, high thermal conductivity, superior dimensional stability, low coefficient of friction for seals and bearings, high coefficient of friction with increasing loads without fade for brakes, and low steady state wear rate.
