English Abstract

This research studied the effect of composite materials reinforced fiber and prepared from material (polyester with various natural fibers) then studied the effect of chemical treatment on the same fiber immerse in (10%) NaOH solution for half an hour and then compared the diffusion properties for two types of solutions and compared the results of the same test for composite materials without and with chemical treatment.

The result shows that solution would be absorbed in the pure then the composite reinforced before treatment and composite reinforced after treatment has the small absorbed and it clear that the type of fiber has an effect in absorbed sisal more than that in hemp, lufa but the palm leaf, because that the fiber/matrix interface plays the role of a channel for a solution to penetrate into the composite; this penetration normally starts at cut edges.

And the diffusivity coefficients of salt water in the materials (under test) have converged compared with that of pure matrices, due to the interface defects or in-homogeneity that exists in the blends and composites.
