摘要

This study explores thePolymer composites potentialCharacterization ofLignocellulosic fibers açaíEuterpe oleracea palm stem fibers (AFPS) as reinforcement in composite materialsComposite materials, aligning with circular economy principles by converting agricultural waste into a valuable resource. AFPS present a sustainable alternative to synthetic fibers such as fiberglass and nylon, owing to their low density, high specific strength and stiffness, biodegradability, and carbon neutrality. As Brazil—the world’s largest açaí producer—faces increasing waste from fruit processing, the valorization of discarded stems offers an environmentally responsible solution. In this research, AFPS extracted from waste stems were characterized in terms of their mechanical (tensile strength), thermal (TGA), microstructural (FTIRFourier-Transform Infrared Spectroscopy (FTIR)), morphological (SEM), chemical, and physical properties. The fibers exhibited a maximum tensile strength of 267.3 MPa and an initial thermal degradation temperature of 278 °C. These results demonstrate the feasibility of using AFPS in compositeComposites applications, reducing dependence on non-renewable resources while promoting sustainable waste management.
