TY - CONF A1 - Theiler, GĂ©raldine T1 - Environmental effects on the sliding behaviour of polymer composites N2 - The tribological behaviour of polyetheretherketone (PEEK) and polyimide (PI) composites was investigated in air, vacuum and hydrogen environments. Polymers were filled with graphite, submicron particles or carbon nano-tubes. Experiments reveal that hydrogen environment has a major influence on both polymer structure and fillers during sliding. The sliding behaviour of these polymer composites is much improved in hydrogen compared to air. In particular, graphite and nano-particles have a remarkable effect on friction and wear, respectively.
