Title (EN) GRADIENT DENSITY SOUND ATTENUATING COMPOSITE AND PROCESS FOR MAKING
(FR) COMPOSITE D'ATTÉNUATION ACOUSTIQUE À GRADIENT DE DENSITÉ ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) A sound attenuating material having a homogenous mixture of an organic man-made fiber, an inorganic man-made fiber, a binder, and a cellulose material wherein the organic man-made fiber is polyester, the inorganic man-made fiber is fiberglass, and the binder is a thermo-setting resin. A sound attenuating composite is defined by the sound attenuating material and a ground EVA or a mixture of EVA and one or more recycled materials to define a gradient density sound attenuating composite material. Further, the gradient density composite may optionally include a polyfilm upon which the ground EVA or recycled materials may be disposed or two layers of polyfilm to surround the EVA or EVA mixture. The EVA may be pure EVA or may include a mineral fill.
(FR) L'invention concerne un matériau d'atténuation acoustique contenant un mélange homogène d'une fibre synthétique organique, d'une fibre synthétique inorganique, d'un liant, et d'un matériau cellulosique, où la fibre synthétique organique est du polyester, la fibre synthétique inorganique est de la fibre de verre, et le liant est une résine thermodurcissable. Un composite d'atténuation acoustique est défini par le matériau d'atténuation acoustique et de l'EVA broyé ou un mélange d'EVA et d'un ou plusieurs matériaux recyclés pour définir un matériau composite d'atténuation acoustique à gradient de densité. En outre, le composite à gradient de densité peut éventuellement contenir un polyfilm sur lequel l'EVA broyé ou les matériaux recyclés peuvent être disposés ou deux couches de polyfilm servant à entourer l'EVA ou le mélange d'EVA. L'EVA peut être de l'EVA pur ou peut contenir une charge minérale.
