Title: Deterioration of Aramid, Glass, and Carbon Fibers Due to Alkali, Acid, and Water in Different Temperatures

Abstract:This paper clarifies, experimentally, the degradation of aramid fiber, glass fiber and carbon fiber, used as reinforcement for concrete, in various solutions (alkaline solution, hydrochloric acid aqueous solution and pure water) at different temperatures. A calculation model is proposed to estimate the progress of the degradation by the solution. The accelerated degradation test, immersing fibers in several solutions, was carried out at the temperatures of 20, 40 and 60 degrees Celsius and the strength of the fiber after the immersion test was examined. Observation of the fibers was carried out by scanning electron microscope (SEM) in order to clarify the degradation of the fibers. As a result of this study, the strength changes of Kevlar 49 and Technora were quantitatively estimated using the weakest link theory of Weibull.
