| Abstract Scope |
The use of lignocellulosic fibers as reinforcement agents in polymer matrices has attracted growing industrial interest due to their potential to replace synthetic fibers such as glass fiber, nylon, and polyamides. These natural fibers offer advantages such as low density, high specific strength and stiffness, biodegradability, and carbon neutrality. Among the alternatives under investigation are fibers extracted from the stem of the açaí palm (Euterpe oleracea), an abundant residue in Brazil—the world’s leading açaí producer. This study investigates the mechanical, thermal, morphological, microstructural, chemical, and physical properties of these fibers. The fibers were evaluated through tensile tests, TGA/DTG, FTIR, SEM, chemical composition analysis, and moisture content. The maximum tensile strength reached 267.3 MPa, with no clear correlation between fiber diameter and strength. Thermal degradation began at 278 °C. The results support the potential application of these renewable fibers as reinforcement in sustainable composite materials. |
