Experimental Study on Effects of Laminated Structure on Acoustic Insulation Property of Composites
In order to study the effects of laminated structure on acoustic insulation property of composites, the frequently-used flexible polyvinyl chloride (EPVC) sheets and non-woven fabric were selected as the substrate materials to prepare for ten types of nonwoven fabric/EPVC composites with different laminated structures in this study. Their acoustic insulation properties were tested and analyzed by the double channel acoustic instrument. The results showed that the different laminated order of composites has significant influence on its acoustic insulation property under the same conditions; and the acoustic insulation property of composites can be improved by the change of laminated order only.
