Abstract

This study explores the feasibility of using industrial hemp fiber to create composite panels—termed Sustainable Hemp Industrial Panels (SHIP) as a potential competitor for oriented strand board (OSB), a commonly used structural wood product. Given hemp's historical and environmental advantages, including rapid growth, carbon sequestration capacity, and material strength, this research investigates its performance when combined with Urea-Formaldehyde (UF) resin, and in a hybrid form with Southern Yellow Pine (SYP). Two hemp-based composites were produced and tested: one with hemp and UF, and another with hemp and SYP. Using a custom-built hydraulic press, composite panels were fabricated and subjected to 3-point flexural tests to assess their mechanical properties relative to OSB. Results showed that while OSB outperformed both hemp composites in structural strength, the hemp-based panels demonstrated favorable toughness and fiber integrity at failure points. Observations indicated that processing methods, resin distribution, and resin type significantly impacted performance outcomes. Although hemp composites did not surpass OSB in current form, this research highlights hemp's potential as a sustainable alternative with further development and optimization.
