With development of smart technical applications many devices and technology are involved to resist the high intensity surrounding noise. High persistence of different noise in environment and living surrounding of human being is a challenging problem now days. Though the different technology and devices are invented to resist the noise level in the living surrounding but still it needs the development of more effective and potential materials. Luffa cylindrical fibre reinforced epoxy composite has significantly enriches this noise reduction property due to its unique and complex networking structure between the each of its single fibre. When a number of multilayered luffa cylindrical fibres reinforced with high sensitive polymer matrix like epoxy, their structural configuration modifies into that extent where the composite can be functioned as effective shielding material for propagation of sound through them. Ultrasonic blended alcohol with tartaric acid plays a significant role for enhancing sound absorption coefficient in addition with strengthening the material by interlocking the luffa fibres with polymeric matrix which is found to be increased significantly with that of alcohol blended chemicals. The SEM and FTIR characterization of both untreated and treated luffa fibre confirms the surface modification which enables the composites to be a good acoustic material. Further, thermal insulation properties are well confirmed and support the attenuation of sound propagation through the material which decreases the thermal and electrical conductivity of the composites.

Abstract


With development of smart technical applications many devices and technology are involved to resist the high intensity surrounding noise. High persistence of different noise in environment and living surrounding of human being is a challenging problem now days. Though the different technology and devices are invented to resist the noise level in the living surrounding but still it needs the development of more effective and potential materials. Luffa cylindrical fibre reinforced epoxy composite has significantly enriches this noise reduction property due to its unique and complex networking structure between the each of its single fibre. When a number of multilayered luffa cylindrical fibres reinforced with high sensitive polymer matrix like epoxy, their structural configuration modifies into that extent where the composite can be functioned as effective shielding material for propagation of sound through them. Ultrasonic blended alcohol with tartaric acid plays a significant role for enhancing sound absorption coefficient in addition with strengthening the material by interlocking the luffa fibres with polymeric matrix which is found to be increased significantly with that of alcohol blended chemicals. The SEM and FTIR characterization of both untreated and treated luffa fibre confirms the surface modification which enables the composites to be a good acoustic material. Further, thermal insulation properties are well confirmed and support the attenuation of sound propagation through the material which decreases the thermal and electrical conductivity of the composites.
