Abstract

Moisture absorption in polymer composites is influenced by internal factors (fibre type, fibre fraction and its orientation) and external factors (relative humidity and temperature). In this paper, the authors report the influence of the internal and external factors on the moisture absorption characteristics (equilibrium absorption and diffusion coefficient), of permeable (jute-epoxy) and impermeable (glass-epoxy) composites.
