Mechanical and Morphological Characteristics Study of Chemically Treated Banana Fiber Reinforced Phenolic Resin Composite with Vajram Resin

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

以天然纤维和天然树脂为主要原料的全天然复合材料的开发是材料时代的挑战之一. 针对这一问题，本研究旨在探讨利用天然树脂金刚砂与天然香蕉纤维开发天然复合材料的可能性. 另外还分析了碱处理对香蕉纤维用 5% 、10% 和 15% 氢氧化钠（NaOH）溶液改善性能的影响. 所有的复合材料都是采用手工叠层技术，然后通过模压成型制备的. 所有机械试验均按相应的 ASTM 标准进行. 实验结果表明, 5%NaOH 处理的纤维比其它纤维的拉伸强度高 170.12mpa. 香蕉纤维增强酚醛树脂复合材料（BFRPC）的拉伸、弯曲和冲击强度分别为 22.62mpa、33.84mpa和 5.87kj/m2. 80%金刚砂掺入香蕉纤维增强复合材料的拉伸、弯曲和冲击强度分别降低21.53%、38.39% 和 44.63%. 这种低强度天然金刚砂树脂-香蕉纤维复合材料非常适合作为非结构件应用于汽车.
