Study diffusion of water to carbon fiber epoxy composite

الملخص EN

In present work moisture diffusion properties of the woven fabric carbon /epoxy laminates were determined using weight gain, experiments over a temperature range of30 C to 60 °C.

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.
