N2 - Efficient storage of hydrogen is crucial for the widespread adoption of renewable energy. Reciprocating piston compressors, featuring advanced sealing solutions, are essential to meet the stringent demands of non-lubricated hydrogen applications, ensuring gas purity and high pressure differentials. Polyphenylene sulfide polymer matrix composites exhibit high mechanical strength and low friction and wear, making them valuable in tribological applications. This study investigates carbon fiber reinforced polyphenylene sulfide modifications with different PTFE contents by employing advanced imaging techniques to assess the effect of dry-lubricant on properties with respect to application in high-pressure reciprocating compressors. Thermo-mechanical and tribological testing, along with microstructure analysis utilizing synchrotron tomography, presents the importance of dry lubricating PTFE additives. Furthermore, the research provides insights into the micromechanical deformation behavior of short fiber reinforced polymers and identifies promising compositions suitable for advanced hydrogen compression.
