Abstract: | 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. |
