摘要

本文的主要议题是开发一种混合现象学模型,用于预测菠萝叶纤维/废茶叶纤维/玻璃纤维/环氧树脂基天然纤维增强混合复合材料的吸声系数。现象学模型擅长推断特征阻抗和波数,而经验模型需要的输入较少,但忽略了波在孔隙中的传播。现有模型仅适用于单纤维增强复合材料,因此有必要为混合复合材料创建一个混合模型。所开发的 Zwikker-Kosten 和 Johnson-Champoux-Allard 混合模型在整个频率范围内与实验数据显示出良好的一致性,标准偏差为 0.001-0.029,百分比偏差为 1.11%-11.43%。模型与实验之间的总体降噪系数为 0.31 vs. 0.30,偏差为 3.33%。此外,碱处理增加了表面粗糙度,进而提高了这些复合材料的吸音能力。纤维粗糙度的增加也扩大了纤维与声波之间的摩擦,从而提高了吸音系数。此外,还对菠萝叶纤维/废茶叶纤维/玻璃纤维/环氧树脂天然纤维增强混合复合材料的指定成分(5%(重量)菠萝叶纤维和 25%(重量)废茶叶纤维)进行了 X 射线衍射、热稳定性(热重分析和差示扫描量热法)和扫描电子显微镜检查。

Adapting a phenomenological model for predicting acoustical behaviour of Camellia sinensis/Ananas comosus/E-glass fibre-blended epoxy hybrid composites
Developing a hybrid phenomenological model for predicting the sound absorption coefficient of a pineapple leaf fibre/waste tea leaf fibre/glass fibre/epoxy-based natural fibre-reinforced hybrid composites is the predominant topic of this article. Phenomenological models excel at extrapolating characteristic impedance and wave number whereas empirical models require fewer inputs but overlook wave propagation in pores. Existing models apply only to single-fibre-reinforced composites, necessitating the creation of a hybrid model for hybrid composites. The developed hybrid Zwikker–Kosten and Johnson–Champoux–Allard model shows good agreement with experimental data across the frequency range, with standard deviations of 0.001–0.029 and percent deviations of 1.11%–11.43%. The overall noise reduction coefficient between the model and experiments is 0.31 vs. 0.30, with a 3.33% deviation. Furthermore, the application of alkali treatment increased the surface roughness which in turn, enhanced the sound absorption capabilities of these composites. The increased fibre roughness also amplified friction between fibres and sound waves, resulting in higher sound absorption coefficients. In addition, X-ray diffraction, thermal stability (thermogravimetric analysis and differential scanning calorimetry), and scanning electron microscopy examinations were performed on the designated composition (5% by weight of pineapple leaf fibre and 25% by weight of waste tea leaf fibre) of the pineapple leaf fibre/waste tea leaf fibre/glass fibre/epoxy-based natural fibre-reinforced hybrid composite.
