Effects of harmonised procedures in (digital) Tribology N2 - The work on Tribology, digitalisation, and the harmonised procedures developed in i-TRIBOMAT Open Innovation Testbed was presented. The project develops procedures and shares ideas on how to deal with characterisation techniques and provide services to end users in different places and locations, which is realised by adopting a common and widely agreed procedures. i-TRIBOMAT is active also via YouTube platform to enhance communication and spread the word amongst the interested parties and society.

The compounds used were a commercial PEEK matrix with 10 wt.% each of PTFE, graphite, and short carbon fibres, a PPS matrix with 10 wt.% each of PTFE and graphite, and an experimental PA12 matrix with PTFE chemically coupled with an oleyl alcohol. Due to the cylindrical shape of the polymer samples, the contact area and pressure change if wear occurs. Therefore, experimental results of pre-screening tests have been used as input for FEM and an analytical model to determine the decreasing contact pressure over time. Afterwards, the outcome of the models was used to determine the duration of the experiments to reach typical contact pressures of seals in hydrogen compressors.
