Definitions
- an intermediate acoustic absorption layer comprising a porous matrix based on flexible foam flakes, in particular derived from recycling, bound together by a binder within which are dispersed particles of dense material, especially derived from recycling, of higher density than that of said matrix,
- reaction injection molding mold Disposing said shell in a reaction injection molding mold (RIM) defining a molding cavity, said backing layer being turned towards said cavity, a space being left vacant between said backing layer and a wall of said cavity,
- RIM reaction injection molding mold
- the absorption is carried out by the intermediate layer, this because of the porosity of the matrix.
- the insulation it is generated by the sealed barrier in combination with the mass imparted to the intermediate layer by the particles of dense material, the assembly being disposed on a foam layer resulting from the molding RIM, so as to achieve a "mass-spring" type insulation.
- a complex comprising a porous fiber-based backing layer, an intermediate layer based on recycled material and a porous location layer, said complex comprising a thermoplastic binder, • heating said complex to melting temperature of said binder,
- said binder being incorporated in said location layer, said location layer having on said panel a basis weight of between 500 and 2000 g / m 2 , the thermoforming of said complex being carried out so that said location layer further comprises :
- At least one highly compressed zone of low absorption said zone having a thickness of between 1 and 3 mm, said thickness being measured according to the NF EN ISO 5084 standard with a presser foot with a surface area of 2000 +/- 20 mm 2 under one pressure of 1 +/- 0.1 kPa.
- the possible existence of at least one zone of weak absorption is linked to the fact that it may be necessary to compress the local layer locally, the compression of said layer being made for example at its periphery, at the periphery of orifices. provided to allow the passage of organs, or to allow the housing of the panel in areas where the reception space of said panel is reduced.
- the location layer may, for certain specific embodiments, not have a highly compressed zone, all of its surface then forming a zone of high absorption.
- the ground material recycled can bring the mass on the sealing barrier to achieve sound insulation according to a "mass-spring" principle.
- the invention proposes a panel obtained by such a method.
- a method of manufacturing a panel 1 acoustic protection for a motor vehicle comprising the following steps: Producing a complex comprising a fiber-based porous backing layer 2, an intermediate layer 3a, 3b based on recycled material and a porous location layer 4, said complex comprising a thermoplastic binder,
- said binder being incorporated in said location layer, said location layer having on said panel a basis weight of between 500 and 2000 g / m 2 , the thermoforming of said complex being carried out so that said location layer further comprises :
- the location layer may, for certain specific embodiments and not shown, not have a highly compressed zone, the entire surface then forming a zone of strong absorption.
- the place layer 4 is based on structural fibers, for example made of polyester, bound together by binder fibers, of "bi" type.
- - component " comprising a core, for example polyester, provided with a fuse sheath, for example co-polyester.
- the binder is based on polypropylene.
- the intermediate layer 3a, 3b has a weight per unit area of between 500 and 1500 g / m 2 .
- the intermediate layer 3a, 3b is based on: Thermoplastic elastomer loaded with a mineral powder,
- the intermediate layer 3a, 3b is put in place by dusting the ground material of recycled material.
- the backing layer 2 has a basis weight of between 50 and 200 g / m 2 .
- the backing layer 2 has a thickness of less than 2 mm.
- the backing layer 2 is a nonwoven.
- zone o optionally at least one highly compressed zone of low absorption 10, said zone having a thickness of between 1 and 3 mm, said thickness being measured according to the standard NF EN ISO 5084 with a presser foot surface 2000 +/- 20 mm 2 under a pressure of 1 +/- 0.1 kPa,
