The effect of diffusion of water into epoxy resins and their carbon-fibre reinforced composites

During normal service water will be absorbed by epoxy resins and fibre-reinforced composites made from them. The rate of water pick-up and the total amount absorbed are governed by the chemical structure of the resin and the cross-linking agent together with the temperature and relative humidity. Th...

Description
Summary:During normal service water will be absorbed by epoxy resins and fibre-reinforced composites made from them. The rate of water pick-up and the total amount absorbed are governed by the chemical structure of the resin and the cross-linking agent together with the temperature and relative humidity. The absorbed moisture causes dimensional changes, generates internal stresses and results in reductions in the heat distortion temperature and certain mechanical properties at elevated temperatures. The magnitude of these effects is surveyed.
