A glass fabric/polyvinyl chloride (PVC) composite material with super thin thickness, lightweight and toughness, was manufactured with the infusion technology under normal pressure. The sound insulation performance of this novel material was determined with a two-channel acoustic analyzer. The structure and mechanical properties were also investigated via SEM, DMA, etc. The results show that the sound insulation properties of the composite material are better than those of the materials with single components, and the loss of the sound transmission through this material exceeds that predicted by the mass law, indicating the composite's good sound insulation properties.
