Sound and Vibration Damping Properties of Water Retted Kenaf Bast Fiber (WKF) and Poly (Butylene Succinate) PBS

Abstract

Nowadays, considerable attention has been paid on the utilization of natural materials to reduce the carbon emission from material synthesis. In this study, the sound and vibration damping properties of natural material based Poly Butylene Succinate(PBS) and Water Retted Kenaf Bast Fiber(WKF) were explored and characterized. The goal is to characterize the sound absorption and damping properties of the PBS and WKF at difference materials percentage. The (material)PBS and WKF are produced by using Compression moulding machine model Gotech GT-7014-H and the sample thickness is 3 mm. The vibration damping measurement of the material is carried out based on the free vibration method technique. It is observed that the damping factor is obtained is 0.0469 for PBS material. The measurement of the sound absorption coefficient of the PBS and WKF is carried out using the impedance tube. The result shows that the maximum sound absorption of 0.305 was observed at a frequency of 642 Hz for PBS material. Whereas Tensile Strength, for PBS material shows 26.33 MPa. These results suggest that the PBS could be a viable candidate for applications which need good sound and vibration properties.
