Resumen
Objectives: This research investigates methods to enhance the adhesion between polymer matrices and plant fiber reinforcements, specifically Alfa fibers (Stipa tenacissima), using a 2 wt % NaOH solution for varying durations (1, 3, 5, and 24 h).
Theoretical Framework: Plant fiber-reinforced composites are increasingly favored for their eco-friendliness, low density, cost-effectiveness, and promising mechanical properties. However, challenges persist due to inadequate adhesion between the polymer matrix and plant fibers, which can compromise composite performance.
Method: Alfa fibers were chemically treated with a 2 wt % NaOH solution for different durations. A comprehensive suite of tests, including FTIR, DRX, GTA, SEM, and tensile tests, were conducted to evaluate the effects of the treatment.
Results and Discussion: XRD analyses revealed a significant increase (36.26%) in the crystallinity index of Alfa fibers treated with a 2 wt % NaOH solution for 5 hours compared to untreated fibers. Moreover, mechanical testing demonstrated that composites reinforced with treated fibers exhibited superior mechanical properties compared to those reinforced with untreated fibers.
Research Implications: These findings highlight the potential for enhancing the performance of plant fiber-reinforced composites through chemical treatments, thereby enabling them to compete effectively with composites utilizing synthetic fibers.
Originality/Value: This study contributes to advancing high-performance composite materials by addressing the critical issue of interfacial adhesion between polymer matrices and plant fibers, thus expanding the application potential of eco-friendly composites in various industries.
