Thermoformable laminate structure with improved acoustical absorption |
摘要 |
A thermoformable laminate structure with improved acoustical absorption is provided which has a first and a third layer of foamed thermoplastic material and a second layer, intermediate the first and third layers, which is a material having acoustical properties different from the properties of the material of the first and third layers. A portion of the surface area of each layer is adhesively bonded to the adjacent layer. A resin impregnated fabric is bonded to the outer surfaces of the first and third layers.
