Local water content field within an epoxy/metal bonded assembly in immersion

Résumé

In this article a model of water diffusion within a bonded assembly will be set up. It will be fed by experimental tests which will allow to characterize the diffusive properties of a bonded assembly by taking into account the presence of interphases. For this purpose, specimens will be instrumented with Fresnel fiber optic sensors. These sensors allow a local measurement of the water content of a polymer material during wet ageing. Once these measurements are performed, the model, which will be called “gradient model”, will then allow to calculate and represent the water content field at the core and at the interphases of an epoxy/metal bonded assembly. This model will be confronted with gravimetric tests in order to verify its good performance on the calculation of the global water content of an assembly.
