Tensile tests were performed at room temperature (RT) in air and in LN2. Tribological experiments were carried out with a pin-on-disc configuration at RT, in LN2, in LH2 and in LHe. PEEK composites have a better tribological performance than PTFE materials especially regarding the wear resistance.

Thus, new material requirements are involved for these tribo-systems, in particular regarding operability and reliability. At BAM, several projects were conducted in the recent years, dealing with the tribological properties of friction couples at cryogenic temperature and in vacuum environment. This paper describes the vacuum and ultra high vacuum tribometers constructed at BAM and presents experiments carried out with polymer composites. The experiments presented were performed with PEEK, filled with solid lubricants, against 304 steel with a pin-on-disc configuration in oscillating sliding. Friction tests were carried out in vacuum in the temperature range between -40°C and +160°C and in ultra high vacuum at room temperature.
