Studies on self-binding hot-pressed fiberboards using agricultural byproducts aim to identify alternatives to scarce wood resources. Particle size and mixture significantly impact strength, although direct comparisons are difficult due to differences in study methods. We evaluated fiberboards made from the two perennial biomass crops and and compared them to (spruce), using five distinct particle size blends prepared from milled and sieved particles, respectively. The boards were evaluated for their modulus of elasticity, modulus of rupture, reaction to fire, water absorption, and thickness swelling. All specimens exhibited normal ignitability, as defined by Euroclass E according to EN13501-1. The results indicate that mechanical performance improves with increasing density, which correlates with higher proportions of finer particles. Notably, the finer blends and all samples met the modulus of elasticity requirements of EN 622.
关于使用农业副产品的自粘结热压纤维板的研究旨在寻找稀缺木材资源的替代品。尽管由于研究方法的差异难以进行直接比较，但颗粒大小和混合物对强度有显著影响。我们评估了由两种多年生生物质作物制成的纤维板，并将它们与云杉进行比较，分别使用从研磨和筛分颗粒制备的五种不同颗粒大小混合物。对这些板材的弹性模量、断裂模量、防火性能、吸水性和厚度膨胀进行了评估。根据EN13501-1标准，所有试样均表现出欧洲等级E所定义的正常可燃性。结果表明，随着密度的增加，机械性能有所改善，这与更细颗粒的比例较高相关。值得注意的是，更细的混合物和所有样本均满足EN 622的弹性模量要求。
