Abstract
In this research have been identified diffusion coefficient of solvents with ratios(0.3salt water) , (0.5sodium hydroxide), (0.5potassium hydroxide), and it was observed melting and mechanisms of moisture in the composite material consisting of fiber glass and polyester it at (70Co)and the results were then compared to samples of composite materials with six layers of fiber to take advantage of comparison in determining the impact of the presence of diffuse temperature and without in most in dustrial applications. The samples were composite material used is composed of two types of fiber type I(fibers woven) and type II(fiber woven + random), and through the results was observed that the solvents basal have a clear impact on composite materials and increases this effect with increasing temperature, as observed that diffuse more in the first type of samples(fiber woven) of the second type of samples (fiber woven + random), in addition to the diffuse coefficient varies from one solution to another, when the temperature increase for type 1and 2 .And the results were recorded the largest percentage value of salt water ( 2.93%,3.02% ) for two types of fiber respectively, which means minimum absorption resistance , followed by sodium hydroxide and finally potassium hydroxide (1.292%,1.05%) respectively because of (maximum absorption resistance).
