Obtaining H interaction parameters for carbon fibre composites by modelling isovolumetric desorption experiments
Carbon fibre composites (CFC) are candidate plasma facing materials. In this paper a non-stationary model is presented which allows determination of the hydrogen D and K, from isovolumetric desorption experiments. For Ni, model predictions and existing results agrees very well. Apparent values for N112, N11, NS31, are obtained. The model was refined to account for CFC's non-homogeneity. The experimental profiles are naturally followed. The determinant role of the fibre on the total K, of H in CFC and on the role of porosity on the hydrogen D and K, in matrix are shown. The model could be used to design CFC from the H transport properties point of view.
