Hybridization Effects on the Mechanical and Aging Behavior of Elium Acrylic‐Based Flax‐Glass Fiber Composites

Résumé

This study examines the hybridization effect of flax–glass fiber‐reinforced Elium acrylic polymer composites, with a particular emphasis on their mechanical properties, viscoelastic behavior, and diffusion kinetics. For this purpose, hybrid composites were fabricated by combining flax and glass fiber laminates with various stacking sequences using vacuum molding and subjected to environmental aging at room temperature. The primary objective was to evaluate the performance of these hybrid composites in comparison to flax fiber laminate composites. The results demonstrate that hybridizing flax fibers with glass fibers significantly mitigates the degradation of mechanical properties induced by aging. Notably, hybrid composites exhibit a significant improvement in both Young's modulus and tensile strength compared to pure flax fiber laminate composites. Dynamic mechanical analysis (DMA) further reveals that hybrid composites achieve marked enhancements in storage modulus and glass transition temperature, indicating improved viscoelastic behavior. Scanning electron microscopy (SEM) analyses performed on post‐tensile and aging tests highlight a reduction in microcrack propagation due to hybridization. These findings underscore the role of glass fibers in enhancing the durability and overall performance of flax fiber composites, making them a promising candidate for applications requiring sustained exposure to aggressive environments.
