The furniture industry is seeking low-impact composite panels with reliable performance. Hemp residues (shives/hurds) offer a high biomass yield and promise carbon-sequestering potential, yet their translation into furniture-grade boards remains underexplored. This study evaluates hemp residues as furnish for interior particleboards and optimizes key pressing parameters—temperature, pressure, and pressing time—across distinct particle-size fractions. Performance is benchmarked against typical requirements for interior applications. We implement a structured experimental design that varies pressing parameters and the fraction of furnish at a controlled panel density and adhesive loading. Mechanical and dimensional responses are assessed using standardized procedures (e.g., static bending, internal bond, and thickness stability), while Digital Image Correlation (DIC) provides full-field strain maps during bending to identify deformation patterns and failure initiation. The dataset will be complemented by process-property relationships derived from the experimental design. The study is expected to delineate a feasible processing window for hemp-residue boards that achieves competitive mechanical performance and improved dimensional stability. The complete experimental results and DIC-based insights will be presented at the conference.
