Abstract: In this research study the Diffusivity behavior and diffusion
coefficient for epoxy composite reinforced with glass fibers , carbon fibers,
and woven Kevlar+carbon fibers with volume fraction 5%,10%,and 15%.
The samples were immersed in different solution for equal time at constant
temperature (room temperature 24ₒC). The result show that the relative mass
gain increased with increasing the immersion time till they tend saturation
moisture mass (M∞) after that the relative mass gain decreased. The result
show that the samples immersed in (kerosene) solution had higher mass gain
while the samples immersed in water. Also the results show that the samples
immersed in Nacl-water solution has maximum diffusion coefficient
(8.84*10-2 mm2/day) which means minimum absorption resistance while the
samples immersed in H2O has minimum diffusion coefficient (0.24 * 10-2
mm2/day) (maximum absorption resistance).
