Sound Insulation Provided by PET Fabric/PVC Composite Materials

Abstract:

Single layer PET Fabric/polyvinyl chloride (PVC) composite materials and double layers PET fabric/polyvinyl chloride (PVC) composite materials with super thin thickness, lightweight, flexible and high strength were manufactured by means of the infusion technology under normal pressure. The sound insulation performance of these novel materials was evaluated with a two-channel acoustic analyzer. The structure and mechanical properties were investigated by mechanical tests and SEM observation. The results show that for the small surface density the double layers composite has better sound insulation performance than that of the single one. But with increment of surface density, the difference between them becomes small, and for the surface density larger than 1.3kg/m2, the sound insulation performance becomes inverse on layers, i.e., the single layer composite has better sound insulation performance than that of double layers one. Therefore, difference structures of composites can be developed based on sound wave features.
