Prediction of long term durability of polymeric composite materials exposed to the acid and high temperature environmental conditions

long term durability of E-glass/vinyl ester composite materials exposed to an acidic solution and high temperature condition are investigated. In this research, the influence of mentioned environmental conditions on the created specimens has been considered experimentally, then, a predictive framework based on Arrhenius relation hasbeen used to illustrate long term behavior. Ambient temperature with an elevated temperature are employed in this research. All specimens are exposed to these conditions for 1, 2, 4 and 8 weeks. Finally bending test is performed in order to find degradation of properties. The effect of acidic solution on the degradation of this kind of composites has been shown and 5.5 years prediction of strength loss is provided.
