Abstract

Water uptake in sorption experiments made on epoxy/carbon fiber composites have been investigated in various temperature conditions. Equilibrium moisture uptake and diffusion rate in hygrothermal cycling were viewed and analyzed as thermodynamic and kinetic processes, respectively. According to Pick's law, the diffusion coefficients of water in sorption/desorption processes were measured and exhibited a linear relationship with the inverse temperature. Equilibrium water uptake was quantitatively analyzed by bound water and free water. The amount of each water were experimentally determined by hygrothermal cycling. Wet T_g decreased by the absorbed moisture and was linearly correlated with the total equilibrium moisture contents.
