ANALYSE THE SOUND ABSORPTION CHARACTERISTICS OF E-GLASS AND KEVLAR FIBER HYBRID COMPOSITE MATERIALS USING IMPEDANCE TUBE

Mechanical Engineering

This paper presents the analysis of sound absorption properties of few natural fibers by using impedance tube. The impedance tube plays a vital role to study the sound absorption co- efficient. The specimen of impedance tube is prepared by handlay up process. In sample A, the fiber combination of 20% agave tequilana and 25% Kevlar fiber along with 55% of epoxy resin and sample B, the another combination of 30% of E - Glass and 15% of bamboo fiber along with 55% of epoxy resin was prepared. In this present work, both the specimens are tested using impedance tube and the results was studied and compared. From those two samples, sample A absorbed the sound absorption coefficient more than the sample B due to the physical properties of agave tequilana and Kevlar fiber.
