Abstract
Abstract PTFE-based materials are widely used in areas of tribology, particularly in seal and bearing applications because of their outstanding self-lubricating properties. This paper concentrates on the viscoelastic response of PTFE-based materials. Using a dynamic mechanical analyzer (DMA), the storage modulus, loss modulus and tan δ, are measured and discussed in the frequency domain. The relaxation modulus and creep compliances are also measured and studied in the time domain. Finally, the materials’ compositions are studied using Energy Dispersive X-ray Spectrometer for composites measurement. The experimental data is then modeled with best fit curves using the Prony series and compared to the experimental data.
