In the development of hydrogen technology, special attention is paid to the technical problems of
hydrogen storage. One possible way is cryogenic storage in liquid form. Generally cryotechnical
machines need components with interacting surfaces in relative motion such as bearings, seals or
valves, which are subjected to extreme conditions. Materials of such systems have to be resistant to
friction-caused mechanical deformation at the surface, low temperatures and hydrogen environment.
Since materials failure can cause uncontrolled escape of hydrogen, new material requirements are
involved for these tribo-systems, in particular regarding operability and reliability. In the past few
years several projects dealing with the influence of hydrogen on the tribological properties of friction
couples were conducted at the Federal Institute for Materials Research and Testing, (BAM), Berlin.
This paper reports some investigations carried out with polymer composites. Friction and wear were
measured for continuous sliding and analyses of the worn surfaces were performed after the
experiments. Tests were performed at room temperature in hydrogen as well as in liquid hydrogen.
