Abstract:This paper presents a comprehensive analysis of the residual thermal and mechanical properties of pultruded GFRP composite rebar following a decade of conditioning in an alkaline solution and exposure to natural weather conditions. The study focuses on evaluating the changes in the glass transition temperature (Tg) of the polymer matrix and its impact on the rebar's mechanical performance. The results indicate that the Tg retained approximately 94.7% of its initial value, with the decrease attributed to the pl… Show more
