发明名称 Multilayer composite material
摘要 The invention concerns a multilayer composite material comprising at least one core (3) interposed between two external layers (1, 2), wherein: —the core (3) is a layer of thermoviscous fluid at room temperature, said thermoviscous fluid having a dynamic viscosity coefficient greater than 100 Pa·s at room temperature, —each external layer (1, 2) is in a material in the solid state at room temperature, each external layer having a surface mass of less than 8 kg/m2.

主权项 1. A multilayer composite material comprising at least one core interposed between two external layers, wherein: the core is a layer of thermoviscous fluid at room temperature, said thermoviscous fluid having a dynamic viscosity coefficient greater than 100 Pa·s at room temperature, the thickness of the thermoviscous fluid layer being less than or equal to twice an acoustic limiting layer of the thermoviscous fluid, each external layer is in a material in a solid state at room temperature, each external layer having a surface mass of less than 8 kg/m2.
