Studying the effect of temperature on the diffusionof alkaline solution in polyester reinforcement by fibersglass

Abstract EN

In this research 0Thave been identified diffusion coefficient of solvents with ratios(0.30Tsalt 0Twater)0T , 0T(0.5sodium hydroxide0T), 0T(0.5potassium hydroxide 0T), 0Tand it was observed melting and mechanisms of moisture in the composite material consisting of fiber glass and polyester it 0Tat 0T(70CPoP)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 applications0T.

The 0Tsamples were composite material used is composed of two types of fiber type I (0Tfibers 0Twoven0T) 0Tand type II (0Tfiber 0Twoven + random0T), and through the 0Tresults was observed that the solvents basal have a clear impact on composite materials and increases this effect with increasing temperature0T, as observed 0Tthat diffuse 0Tmore in 0Tthe first type of samples (0Tfiber 0Twoven0T) 0Tof the second type of samples (0Tfiber 0Twoven + random0T), 0Tin 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).
