Reusing agro-industrial waste does not only help to mitigate environmental impact but also enables valorization through the development of new products. The aim is to enhance the physical and mechanical properties of particleboard panels produced with Eucalyptus wood and different proportions of waste products-coconut fiber (Cocos nucifera L.). Physical properties (density, water absorption, and thickness swelling) and mechanical properties (static bending and internal bond resistance) were assessed, and panels reinforced with coconut fiber showed the best qualities with higher density, greater dimensional stability, and less water absorption. Static bending resistance and internal bond resistance also increased significantly. This demonstrated the potential of achieving compatible characteristics for civil construction and furniture production through the inclusion of waste material. The impact of this research is obtained from the utilization of an important agro-industrial residue in the manufacture of permanent composites.
重复利用农业产业废弃物不仅有助于减轻环境影响,还有助于通过开发新产品实现其价值。其目的是提高以桉树木材和不同比例的废弃物(椰壳纤维)为原料生产的刨花板的物理和机械性能。评估了物理性能(密度、吸水率和厚度膨胀率)和机械性能(静曲强度和内结合强度),结果表明,用椰壳纤维增强的刨花板具有更好的质量,密度更高,尺寸稳定性更好,吸水率更低。静曲强度和内结合强度也显著提高。这表明通过加入废弃物,可以实现用于民用建筑和家具生产的具有兼容性的特性。这项研究的影响来自于在制造永久性复合材料中利用重要的农业产业废弃物。
