Abstract

Natural fiber composites often exhibit significant acoustic behavior in low-frequency range. The focus of this study is to create soundproof panels using luffa and Kevlar fiber composites reinforced using nanoclay (MMT) filler. Mechanical testing was performed on the prepared samples. The addition of 4% MMT improved the mechanical characteristics. Mechanical parameters such as interlaminar shear, tensile, flexural, and impact strength were enhanced by 9.13%, 16.89%, 9.71% and 51.64%, respectively, as compared to the control sample. Tribological experiments were performed on the manufactured composite samples in dry sliding conditions as a function of control factors such as sliding speed, sliding distance, and effective load. The results reveal that using 6% MMT to Kevlar/LCF epoxy composites greatly increases the COF and specific wear rate. The sound absorption test results indicated that the incorporation of nano MMT with Kevlar/LCF composites increased the sound transmission loss. The reduced hydrophilicity effect has been reported with the addition of 4% (by weight) MMT in contact angle measurement studies. Moreover, the created biocomposites are low-cost and long-lasting materials suitable for use as soundproofing panels in automobiles and railway cabins.

丝瓜和凯夫拉纤维/纳米粘土可持续热固性生物复合材料:声学和三力学研究
天然纤维复合材料通常在低频范围内表现出明显的声学特性。本研究的重点是利用纳米粘土(MMT)填料增强的丝瓜纤维和凯夫拉纤维复合材料制作隔音板。对制备的样品进行了机械测试。添加 4% 的 MMT 改善了力学特性。与对照样品相比,层间剪切、拉伸、弯曲和冲击强度等力学参数分别提高了 9.13%、16.89%、9.71% 和 51.64%。在干滑动条件下,对制造的复合材料样品进行了摩擦学实验,实验结果与滑动速度、滑动距离和有效载荷等控制因素有关。结果表明,在 Kevlar/LCF 环氧树脂复合材料中添加 6% 的 MMT 可大大提高 COF 和比磨损率。吸音测试结果表明,在 Kevlar/LCF 复合材料中加入纳米 MMT 增加了声音传输损失。据报道,在接触角测量研究中,添加 4%(按重量计)的 MMT 可降低亲水性效应。此外,这种生物复合材料成本低、使用寿命长,适合用作汽车和铁路车厢的隔音板。
