In present work moisture diffusion properties of the woven fabric carbon/epoxy
laminates were determined using weight gain, experiments over a temperature range of
30 0C to 60 0C. The laminate–shaped fiber reinforced composites were manufactured by
using epoxy resin (Epon 828) cured with TETA (tri ethylene tetra amine) reinforced with
carbon fiber. The prepared Composite samples were immersed in water for several
weeks and moisture content was measured. The diffusivity of the composite was found
to obey the Arrhenius relation over the entire range of temperature. Analytical solution to
Fick’s law is done by build up computer program in Matlab. Good agreement between
experiment data and analytical solution of Fick’s Law.
