Development and Study of Acoustic Properties of Desmostachya Bippinata Reinforced Composite

In this study, the objective was to produce a rein¬forced composite of desmostachya bipinnata(Halfa grass) fibre with the adequate epoxy resin and Hardener of 10:1 ratio for an acoustic application. The use of acoustic panels is one of the most important methods for sound insulation in buildings. The composites were developed using vacuum bag technique with different fibre diameter ranging from 53 microns to 1700 microns. In the present study developed composites were examined for sound absorption coefficient (SAC). It has been found that by increasing the fiber content, the sound absorption coefficient (SAC) also increases. The natural fiber-based composites can be used in building interiors, automotive body parts and house¬hold furniture. Such composite development is an ecofriendly approach to the acoustic world.
