ABSTRACT

The development of complete natural composite with natural fiber and natural resin is one of the challenges in the material era. To address the issue, this research article is aimed to study the possibility of utilizing the natural resin Vajram with natural banana fiber to develop a natural composite. In addition to that alkali treatment of banana fiber with 5%, 10% and 15% sodium hydroxide (NaOH) solution to improve the properties also analyzed. All the composites were prepared using a hand layup technique followed by compression molding. All the mechanical testings were conducted as per corresponding ASTM standards. The experimental results showed that 5% NaOH treated fibers recorded higher tensile strength 170.12 MPa than other fibers. Banana fiber reinforced phenolic resin composite (BFRPC) with 5% NaOH treated fibers with a 30% fiber weight ratio recorded the highest mechanical properties such as 22.62 MPa, 33.84 MPa, and 5.87 kJ/m² in tensile, flexural, and impact strength respectively. 21.53%, 38.39%, and 44.63% reduction in tensile, flexural, and impact strength respectively were noted due to the 80% Vajram mixed banana fiber-reinforced composite. This kind of low strength natural Vajram resin mixed banana fiber composites is well suitable for automobile applications as non-structural components.

摘要

开发天然纤维和天然树脂的完全天然复合材料是材料时代的挑战之一。为了解决这个问题，本文旨在研究利用天然树脂 Vajram 与天然香蕉纤维开发天然复合材料的可能性。除了用 5%、10% 和 15% 的氢氧化钠 (NaOH) 溶液对香蕉纤维进行碱处理以改善性能外，还分析了这些问题。所有复合材料均使用手糊技术制备，然后进行压缩成型。所有机械测试均按照相应的 ASTM 标准进行。实验结果表明，经 5% NaOH 处理的纤维比其他纤维具有更高的拉伸强度 170.12 MPa。抗拉强度、抗弯强度和冲击强度分别为^{2 。}由于 80% Vajram 混合香蕉纤维增强复合材料，拉伸、弯曲和冲击强度分别降低了 21.53%、38.39% 和 44.63%。这种低强度天然 Vajram 树脂混合香蕉纤维复合材料非常适合作为非结构部件的汽车应用。
