In this thesis, we explored the potential of using grapevine canes as raw material for bio-composites. The research aimed to determine the optimal parameters for making these boards and to assess their mechanical properties and moisture resistance. We tested various combinations of tannin adhesive with short and long grapevine canes and phenol-formaldehyde adhesive. Multiple test boards were produced, varying the amount of adhesive, the length of the canes, and the layer ratios. The results showed that boards made with phenol-formaldehyde adhesive exhibited better mechanical properties and lower moisture sensitivity, while tannin adhesive boards were more environmentally sustainable but less moisture-resistant. The final board, made with the optimal parameters, achieved the best mechanical properties and moisture resistance. We measured the density, bending strength, delamination strength, thickness swelling, and water absorption. We concluded that using grapevine canes for bio-composites is a sustainable solution that could reduce vineyard waste and offer an eco-friendly alternative to traditional wood composites. Our research confirms that grapevine canes can be effectively used as raw material for producing high-quality bio-composites.
