Sound Insulation Characteristics of the Embedded and Co-Cured Composite Damping Structures

Abstract:

Based on the designable mechanical characteristics of composite structure, a secondary vulcanization method of viscoelastic material is developed to manufacture the experimental specimens of embedded and co-cured composite damping structure (ECCDS). The mid-temperature co-cured process of the composite material embedding viscoelastic damping membrane is explored according to the glass fabric/epoxy composite cure cycle. By using a standing wave tube method, sound insulation performance of the composite damping structure is tested and compared with the composite laminates without the damping layer. The conclusion indicates that ECCDS has a very strong potential to insulate sound.
