Description 1249-1258
The idea of low cost green thermoacoustic composites urge special attention as an alternative candidate for synthetic
composites in designing of sound proof and highly flexural components for pollution free electric vehicle and other
automotive industries. Short randomly oriented rattan fiber has significant contribution in development of high strength to
weight ratio composite with high frequency dispersion capability. The present work employs the hand layup method for
synthesis followed by ultrasonic cavitation for surface treatment with compatible methanol blended acrylic acid. The
Scanning-Electron-Microscopic (SEM) and Fourier Transform Infrared (FTIR) spectroscopic characterization confirmed the
reorientation of different functional groups which facilitate the sound absorption and mechanical properties. The composite
with admissible tensile strength 47.5 MPa and high flexural property 121.89 MPa along with 30 HV hardness value has
quite distinguishable mechanical characteristics for the fabricated composites. The unique characteristic sound absorption
feature of the rattan fiber composite supports the acoustic behaviour with sound absorption coefficient (SAC) of 97%
classifies as Class-A type as per ASTM C423-17 standard. A continuous mass loss of 69% from 390.89°C to 475°C is well
supported by thermo gravimetric analysis. The regression analysis provides the optimum mechanical performance for which
the composites execute its accuracy. Low sound transmissibility of the composite enhances its acoustic performance. The
thermo-acoustic insulating properties such as thermal conductivity and acoustic behaviour of the materials are well
described converting the rattan fiber for sustainable and eco-friendly applications.
