| Abstract | Fluorosilicone is an elastomer used for the sealing of sensitive parts for which the long term (decades) mechanical integrity should be ensured. The sealing quality is essentially dependent on the quasi-incompressibility of the material, this property being supposed to be constant during the whole service life. The present study consists of, first, the determination of the bulk modulus of the materials under study using a dedicated experimental setup. Then its time dependency (viscoelasticity) will be analysed together with the influence of the ageing on both mechanical properties : shear and bulk moduli. A methodology allowing the prediction of the lifetime under sustained load will be proposed for a demonstrator subjected to a gradient of ageing. |
