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.
