Outline of Final Research Achievements

Indentation creep testing was carried out using TMA with Berkovich indenter to evaluate the viscoelastic characteristics of particle-reinforced PTFE composites. Specimens were prepared with PTFE matrix with 40, 50, 60 weight percentage of aluminum oxide particles. The time-temperature superposition principle was applied to obtain the master curve of the creep compliance of these composites at elevated temperature. The elastic-viscoelastic correspondence principle was also applied to estimate the gasket creep strain in the flanges from the master curve of the creep compliance. Estimation of the gasket creep strain rate in the flanges at 160°C showed a good agreement with the experiment data obtained by the HPIS Z105 test procedure for sealing behavior of gaskets at elevated temperature. The effect of weight percentage of particles on the sealing performance was also evaluated.
