Physico-mechanical characterization of fiberboards made from African locust bean pod fiber using two ecological tannic binders

Year: 2025

Type: article

Abstract: This study explores the valorization of agricultural residues, specifically African locust bean pod fibers and tannic powders extracted from their husks and Indian tamarind peels, for the development of eco-friendly fiberboards. Two fiber size ranges (0.8–1.6 mm and 1.6–2 mm) were used to produce panels with different binder types and tannin contents. The physical properties (density, thickness swelling and water absorption) and mechanical properties (modulus of elasticity, modulus of rupture and tensile strength) of the fiberboards were evaluated. Results revealed that the fiberboards can be classified as Medium Density Fiberboards (MDF) according to the ANSI A208.1–2022 standard. While the water resistance did not meet the standard requirements, the mechanical performance significantly exceeded the thresholds, particularly in terms of stiffness and strength. These findings highlight the potential of underutilized agricultural residues and natural tannin-based binders in the development of sustainable bio-based panels for future material applications.
