Medium density fiberboards were fabricated using a dry, batch process containing various proportions of waste feather fibers bonded with isocyanate-based resin, and overlaid with Acacia mangium Willd. veneers. Physical and mechanical properties of fabricated boards were determined following standard procedures of the American Society for Testing and Materials. Results of the study showed that increasing isocyanate content from 12.5% to 50% and overlaying the chicken feather fiberboards with Acacia mangium veneers improved stiffness (modulus of elasticity) and strength (modulus of rupture). Similarly, improved dimensional stability as indicated by lower thickness swelling and reduction in water absorption were obtained in boards containing isocyanate resin from 12.5% to 50%. Chicken feather fiberboards overlaid with Acacia mangium veneers and with 50% isocyanate content exceed the modulus of rupture and modulus of elasticity values set by the American National Standard for MDF and the ANSI/AHA A 135.4 - 1995 hardboard physical property requirements.
