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.
