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

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