Abstract:
Biodegradable particleboards made from agricultural waste are emerging as sustainable alternatives to conventional wood-based materials. This study developed high-performance particleboards using alkaline-treated corn husk fibers and chitosan adhesive, a natural alternative to formaldehyde-based resins. Alkaline pretreatment improved fiber wettability by removing lignin, hemicellulose, and impurities, enhancing fiber-adhesive interaction. Chemical modifications were analyzed using FTIR and XRD, while contact angle measurements confirmed increased hydrophilicity. Mechanical testing showed significant improvements, with tensile and flexural strengths reaching 49.9 MPa and 56.8 MPa, respectively. SEM analysis revealed a well-bonded fiber-matrix interface, indicating strong adhesion. This approach demonstrates a scalable, eco-friendly method for producing biodegradable composites with superior mechanical performance. Future work will explore enhancing water resistance and assessing industrial-scale production feasibility.
