“…This unit‐cell model has successfully determined the mechanical and nonmechanical (e.g., thermo‐viscoelastic, piezoelectric, and heat conduction) response of FRP composites . Recent studies showed that the unit‐cell model can be formulated to predict the anisotropic fluid diffusion behaviors in FRPs (Gagani et al and Fan et al ). The first subcell is the fiber constituent and the remaining three subcells are matrix.…”

“…To determine the diffusion behavior and diffusivity of the homogenized composite, micromechanical relations between the subcells need to be obtained, as discussed by Gagani et al and Fan et al . With the micromechanical relations, which impose compatibility of the fluid concentration and continuity of the flux at the interface, the concentration matrix is obtained for each subcell.…”

This study presents a multiscale analysis for describing the fluid diffusion in polymeric sandwich composites, comprising of glass-epoxy fiber reinforced polymer (FRP) skins and polyurethane foam core. The multiscale framework includes the unit-cell micromechanics model for determining the overall diffusion behavior in the FRP skins by incorporating different diffusivities of the fiber and matrix and the diffusion model for foam core. In addition, multiscale diffusion tests have been conducted for the sandwich composites, FRP skins, foam core, and epoxy resin. The specimens were immersed in deionized water at 50 C. The capability in predicting the overall diffusion behavior of sandwich composites while recognizing the different diffusion processes of the constituents is not only beneficial for designing polymeric sandwich composites with desired performance but also enhances understanding on the durability of polymeric sandwich composites.
