Moisture solubility and diffusion in epoxy and epoxy-glass composites

The solubility and kinetics of moisture transport mechanisms in epoxy-type resin and resin-glass composites have been investigated over a range of partial pressure and temperature. Moisture absorption-desorption in these systems is a quasi-reversible process, the kinetics of which are non-Fickian (Type II) and dependent on prior history. The multistaged sorption and transport behavior are interpreted in terms of multiphase models.
