Development of Recycled Natural Fiber Based Composite Material by Hand Lay-Up Process and Analysis of Its Acoustic & Physical Properties

ABSTRACT

This research mainly characterizes a unique property of both jute and coir fiber composites. The target of the paper was to justify that unique characteristic, which featured to be the sound absorption quality of those two fiber composites. The composites involved jute and coir fibers as reinforcement and epoxy resin as polymer matrix. The analysis of the binding capability of epoxy resin and its ability to provide net shape to the composites was also an important concern for this paper. Composites of both 100% jute and coir fiber and hybrid composites of different compositions of both fibers were the elements which had gone through the sound absorption test. The proper identification of the chemical composition of the fibers and the realization of the effect of silica gel coating applied on two of the pretreated fiber samples were also some of the distinctive facts and FTIR was performed to examine that. The strength of the composites was also observed. The outcome of the sound absorption test included that, the value of the sound absorption co-efficient changed with the variety in percentage of the fibers present. There also lied a significant difference in sound absorption quality of both the pure fiber composites.

摘要

本研究主要描述了黄麻和椰壳纤维复合材料的独特性能. 本文的目的是证明这两种纤维复合材料的吸声性能的独特性. 该复合材料以黄麻和椰壳纤维为增强材料, 环氧树脂为聚合物基体. 分析环氧树脂的结合能力及其为复合材料提供净形状的能力也是本文关注的一个重要问题. 100%黄麻和椰壳纤维的复合材料以及两种纤维组成不同的混杂复合材料是经过吸声测试的元件. 对纤维化学成分的正确识别以及对两个预处理纤维样品施加硅胶涂层的效果的实现也是一些独特的事实, 并通过FTIR进行了检验. 还观察了复合材料的强度. 吸声测试的结果包括, 吸声系数的值随纤维百分比的变化而变化. 两种纯纤维复合材料的吸声性能也存在显著差异.
