| Abstract Scope |
The search for sustainable materials has driven the development of polymer composites reinforced with lignocellulosic natural fibers, due to their low density, renewable origin, biodegradability, and lower cost compared with synthetic reinforcements. Among these fibers, fique shows high potential for application in epoxy matrices, especially when used in fabric form. However, the hydrophilic nature of plant fibers may impair adhesion with the polymer matrix, limiting the mechanical performance of the composite. In this study, the influence of alkaline treatment with sodium hydroxide (NaOH) on the Izod impact strength of epoxy composites reinforced with sisal fabric was evaluated. The results were analyzed by analysis of variance (ANOVA) and Tukey’s test. The statistical analysis confirmed a significant difference between the evaluated groups. Thus, the alkaline treatment proved to be effective in improving the impact response of epoxy/sisal composites, possibly due to enhanced fiber–matrix interfacial adhesion. |
