A big challenge in the composites industry is the availability of cheap raw lignocellulosic materials, potential candidates to replace slow growing trees, in order to minimize the production cost. Therefore, a variety of plants were studied and tested worldwide in composites manufacturing. The objective of this study was to investigate the technical feasibility of manufacturing particleboards from seaweed leaves (Possidonia oceanica—PO). The use of such a material may benefit both socioeconomic and environmental development since these leaves settle on seashores and decay. The results showed that an incorporation of up to 10% PO leaves did not significantly affect the mechanical properties of the board. Internal bond strength was more severely affected than the other mechanical properties. The incorporation of PO leaves up to 25% did not significantly improve the dimensional stability of the boards. Markedly, boards made from 50% wood particles and 50% PO leaves showed the best thickness swelling values. It is suggested that higher resin dosage and an alternative resin system, such as isocyanates, may improve the panel properties.

海藻（Posidonia oceanica）作为木质复合材料制造的替代木质纤维素原料的潜在用途

复合材料行业的一大挑战是廉价木质木质纤维素原料的可用性，这是替代生长缓慢的树木的潜在候选者，以最大程度地降低生产成本。因此，全世界在复合材料制造中对各种工厂进行了研究和测试。这项研究的目的是研究用紫菜叶制造刨花板的技术可行性（Possidonia oceanica—PO）。这种材料的使用可能有益于社会经济和环境发展，因为这些叶子落在海边并腐烂。结果表明，掺入最多10％的PO叶不会显着影响纸板的机械性能。内部粘合强度比其他机械性能受到的影响更大。最多添加25％的PO叶并没有显着改善木板的尺寸稳定性。明显地，由50％的木材颗粒和50％的PO树叶制成的木板显示出最佳的厚度溶胀值。建议较高的树脂用量和替代的树脂体系（例如异氰酸酯）可以改善面板性能。
