    Abstract

    Epoxy composite laminates absorb moisture from the atmosphere via a diffusion controlled process and undergo changes in both mechanical properties and dimensional shapes. This paper reviews the nature of moisture absorption by epoxy composites and the resultant effects upon the laminate.

    Keywords:

    composite materials, moisture, absorption, diffusion, polymers, swelling, glass transition temperature
