Book Description
Experiments were conducted with a 0.1875-inch- (0.476-cm- ) radius hemisphere of nine polymers in sliding contact with a rotating 17-4 PH disk in liquid hydrogen. Sliding velocity was 2300 feet per minute (701 m/min) at a load of 1 kilogram. Results indicate that several filled polymers show promise. Graphite-filled polyamide (nylon), graphite filled and glass-fiber-filled polytrifluorochlorethylene (PTFCE) and a 50-percent poly-tetrafluoroethylene (PTFE) - 50-percent polyparaphenyl have friction and wear similar to filled-PTFE composites commonly used in cryogenic applications.
