Description

L'invention concerne un panneau d'habillage intérieur de véhicule automobile et un procédé de réalisation d'un tel panneau. Il est connu de réaliser un panneau d'habillage intérieur de véhicule automobile - notamment sous forme d'une tablette de recouvrement d'un compartiment à bagages -, ledit panneau comprenant une âme structurelle, ladite âme présentant une partie centrale et une partie périphérique, ladite âme comprenant, juxtaposées l'une sur l'autre : - une couche fibreuse thermo-comprimée à base de fibres de verre liées entre elles par un liant thermoplastique, - une couche de mousse de polyuréthanne, ladite couche s'étendant uniquement en ladite partie centrale, ledit panneau comprenant en outre : - une couche de revêtement d'endroit - notamment sous forme d'aiguilleté - recouvrant ladite couche fibreuse, - une couche de revêtement d'envers - notamment sous forme de non tissé - recouvrant ladite couche de mousse et ladite couche fibreuse en partie périphérique.The invention relates to an interior trim panel of a motor vehicle and a method of producing such a panel. It is known to produce an interior trim panel of a motor vehicle - in particular in the form of a covering tablet of a luggage compartment - said panel comprising a structural core, said core having a central portion and a peripheral portion, said core comprising, juxtaposed one on the other: - a thermo-compressed fibrous layer based on glass fibers bonded together by a thermoplastic binder, - a layer of polyurethane foam, said layer extending only in said central portion, said panel further comprising: - a location coating layer - particularly in the form of needled material - covering said fibrous layer, - a backing coating layer - especially in the form of a nonwoven - covering said layer of foam and said fibrous layer at the peripheral portion.

La couche fibreuse forme la structure de l'âme, afin qu'elle soit autoportante, et présente usuellement une masse surfacique comprise entre 1500 et 2200 g/m2. Quant à la couche de mousse, elle est destinée à réaliser une protection acoustique par absorption des ondes sonores et présente usuellement une masse surfacique comprise entre 650 et 1000 g/m2. Le panneau obtenu présente donc usuellement une masse importante. La couche de mousse est notamment fixée par collage à la couche fibreuse, qui a été préalablement thermo-comprimée, ledit collage constituant une opération à part entière qui ajoute à la complexité de réalisation du panneau.The fibrous layer forms the structure of the core, so that it is self-supporting, and usually has a weight per unit area of between 1500 and 2200 g / m2. As for the foam layer, it is intended to provide acoustic protection by absorption of sound waves and usually has a weight per unit area of between 650 and 1000 g / m2. The panel obtained therefore usually has a large mass. The foam layer is in particular fixed by bonding to the fibrous layer, which has been previously thermo-compressed, said bonding constituting a separate operation which adds to the complexity of producing the panel.

Ceci étant, un tel agencement permet de prévoir que les couches de revêtement se rejoignent bord à bord selon une ligne de jonction, de manière à masquer la tranche de l'âme, lesdites couches de revêtement étant tranchées au raz de ladite tranche et de ladite ligne, ce qui permet de bénéficier d'une finition périphérique satisfaisante et simple à réaliser. Afin de s'affranchir de l'étape spécifique de fixation de la couche de mousse sur la couche fibreuse, on pourrait prévoir que ladite couche de mousse s'étende sur toute la surface de ladite couche fibreuse.That being so, such an arrangement makes it possible to provide for the coating layers to meet edge-to-edge along a junction line, so as to mask the edge of the core, said coating layers being cut off from said edge and said edge. line, which allows to benefit from a peripheral finish satisfactory and simple to achieve. In order to overcome the specific step of fixing the foam layer on the fibrous layer, it could be provided that said foam layer extends over the entire surface of said fibrous layer.

Ceci permettrait de fixer la couche de mousse sur la couche fibreuse lors de l'étape de thermocompression, sans être confronté au problème du positionnement de ladite couche de mousse par rapport à ladite couche fibreuse avant la thermocompression proprement dite.This would make it possible to fix the layer of foam on the fibrous layer during the thermocompression step, without being confronted with the problem of positioning said layer of foam with respect to said fibrous layer before thermocompression proper.

Cependant, il serait nécessaire, afin de masquer la tranche de l'âme en sa périphérie, de prévoir une bavette périphérique saillante - et peu esthétique - formée par la superposition des couches de revêtement d'endroit et d'envers.However, it would be necessary, in order to hide the edge of the soul at its periphery, to provide a projecting peripheral flap - and unsightly - formed by the superposition of the coating layers of place and back.

En effet, une réalisation où les couches de revêtement se rejoindraient bord à bord selon une ligne de jonction, de manière à masquer la tranche de l'âme, lesdites couches de revêtement étant tranchées au raz de ladite tranche et de ladite ligne, n'est pas souhaitable.Indeed, an embodiment where the coating layers would join edge to edge along a junction line, so as to mask the edge of the core, said coating layers being sliced in the raz of said wafer and said line, n ' is not desirable.

En effet, la couche de mousse ne présente pas une robustesse suffisante pour éviter le risque d'un arrachement de la couche de revêtement d'envers pendant la durée de vie du panneau. Afin de disposer d'une finition périphérique plus satisfaisante, il pourrait être prévu un retour de la bavette vers la couche de mousse, ladite bavette étant alors soudée ou collée contre le revêtement d'envers pour pouvoir être maintenue en place.Indeed, the foam layer does not have sufficient strength to avoid the risk of tearing of the backcoating layer during the life of the panel. In order to have a more satisfactory peripheral finish, it could be provided a return of the flap to the foam layer, said flap then being welded or glued against the backing to be held in place.

Mais une telle réalisation suppose, lors de la fabrication du panneau, une étape spécifique de soudage ou collage de la bavette. L'invention a pour buts de pallier ces inconvénients en proposant un panneau léger, présentant de bonnes propriétés de protection acoustique, de fabrication simplifiée et pourvu d'une finition périphérique esthétique et robuste obtenue de façon particulièrement simple. A cet effet et selon un premier aspect, l'invention propose un panneau d'habillage intérieur de véhicule automobile - notamment sous forme d'une tablette de recouvrement d'un compartiment à bagages -, ledit panneau comprenant une âme structurelle, ladite âme présentant une partie centrale et une partie périphérique, ladite âme comprenant, juxtaposées l'une sur l'autre : - une couche fibreuse thermo-comprimée à base de fibres de verre liées entre elles par un liant thermoplastique, - une couche de mousse de polyuréthanne, ledit panneau comprenant en outre : - une couche de revêtement d'endroit - notamment sous forme d'aiguilleté - recouvrant ladite couche fibreuse, - une couche de revêtement d'envers - notamment sous forme de non tissé - recouvrant ladite couche de mousse, ledit panneau présentant en outre les caractéristiques suivantes : - ladite couche de mousse s'étend sur toute la surface de ladite couche fibreuse, - ladite couche de mousse est fortement comprimée sur ladite partie périphérique, de manière à présenter une épaisseur résiduelle inférieure ou égale à 0,5 mm - étant notamment inférieure ou égale à 0,2 mm -, de sorte que l'épaisseur de ladite âme en ladite partie périphérique soit essentiellement constituée par l'épaisseur de ladite couche fibreuse, - lesdites couches de revêtement se rejoignent bord à bord selon une ligne de jonction, de manière à masquer la tranche de ladite âme, lesdites couches de revêtement étant tranchées au raz de ladite tranche et de ladite ligne. Avec l'agencement proposé, il est possible, notamment par l'utilisation de mousses de très faible densité avant thermocompression, d'obtenir des panneaux allégés par rapport à ceux de l'art antérieur. Par ailleurs, l'association de la couche de mousse à la couche fibreuse peut être faite pendant l'étape de thermocompression, ce qui évite toute opération ultérieure de fixation de ladite couche de mousse par collage ou procédé analogue. Enfin, la finition périphérique est obtenue par une simple opération de découpe.But such an embodiment assumes, during the manufacture of the panel, a specific step of welding or gluing the flap. The invention aims to overcome these disadvantages by providing a lightweight panel, having good acoustic protection properties, simplified manufacturing and provided with an aesthetic and robust peripheral finish obtained in a particularly simple manner. For this purpose and according to a first aspect, the invention proposes an interior trim panel for a motor vehicle - in particular in the form of a covering shelf of a luggage compartment - said panel comprising a structural core, said core presenting a central portion and a peripheral portion, said core comprising, juxtaposed one on the other: - a thermo-compressed fibrous layer based on glass fibers bonded together by a thermoplastic binder, - a layer of polyurethane foam, said panel further comprising: - a location coating layer - particularly in the form of needle punch - covering said fibrous layer, - a backing coating layer - especially in the form of a nonwoven - covering said foam layer, said panel further having the following features: - said layer of foam extends over the entire surface of said fibrous layer, - said layer of foam is highly compressed on said peripheral portion, so as to have a residual thickness less than or equal to 0.5 mm - being in particular less than or equal to 0.2 mm -, so that the thickness of said core in said peripheral portion consists essentially of by the thickness of said fibrous layer, - said coating layers join edge to edge along a junction line, so as to mask the edge of said core, said coating layers being cut off from said edge and said line . With the proposed arrangement, it is possible, in particular by the use of foams of very low density before thermocompression, to obtain panels lightened compared to those of the prior art. Furthermore, the association of the foam layer with the fibrous layer may be made during the thermocompression step, which avoids any subsequent operation of fixing said foam layer by gluing or similar process. Finally, the peripheral finish is obtained by a simple cutting operation.

Elle présente une esthétique optimale, du fait de la jonction des revêtements bord à bord selon une ligne, aucune bavette - avec retour ou non - n'étant prévue pour réaliser la finition. Enfin, la mousse comprimée à une épaisseur résiduelle très faible présente une grande solidité, liée à sa grande compacité, le revêtement d'envers ne présentant plus le risque d'être arraché au cours de l'utilisation du panneau. Selon un deuxième aspect, l'invention propose un procédé de réalisation d'un tel panneau.It has an optimal aesthetic, because of the junction of the edge-to-edge coatings along a line, no bib - with return or not - being provided to achieve the finish. Finally, the foam compressed to a very low residual thickness has a high strength, related to its high compactness, the backing no longer has the risk of being torn during use of the panel. According to a second aspect, the invention proposes a method of producing such a panel.

D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe qui est une vue schématique partielle en coupe d'un panneau selon une réalisation.Other features and advantages of the invention will become apparent in the description which follows, made with reference to the attached figure which is a partial schematic sectional view of a panel according to one embodiment.

Selon une réalisation, la couche de mousse 6 présente une masse surfacique inférieure ou égale à 300 g/m2, ce qui lui permet d'être comprimée jusqu'à une épaisseur résiduelle très faible en partie périphérique 4. Selon une réalisation, la couche fibreuse 5 présente en partie périphérique 4 une épaisseur inférieure ou égale à 4 mm, étant notamment inférieure ou égale à 3 MM.A panel 1 for interior trim of a motor vehicle - in particular in the form of a covering tablet of a luggage compartment - is described below, said panel comprising a structural core 2, said core having a central portion 3 and a peripheral part 4, said core comprising, juxtaposed one on the other: - a fibrous layer 5 thermo-compressed based on glass fibers bonded together by a thermoplastic binder, - a layer of polyurethane foam 6, said panel further comprising: - a location coating layer 7 - especially in the form of needle punch - covering said fibrous layer, - a backing layer 8 - especially in the form of a nonwoven - covering said foam layer, said panel further having the following features: - said layer of foam extends over the entire surface of said fibrous layer, - said layer of foam is strongly compressed on said portion peripheral, so as to have a residual thickness less than or equal to 0.5 mm - being in particular less than or equal to 0.2 mm -, so that the thickness of said core in said peripheral portion is essentially constituted by the thickness of said fibrous layer, - said coating layers join edge to edge along a junction line 10, so as to mask the wafer 11 of said core, said coating layers being trenched in the raz of said wafer and said line. According to one embodiment, the foam layer 6 has a basis weight less than or equal to 300 g / m2, which allows it to be compressed to a very small residual thickness in the peripheral portion 4. In one embodiment, the fibrous layer 5 has a peripheral portion 4 a thickness less than or equal to 4 mm, being in particular less than or equal to 3 MM.

Selon la réalisation représentée, la partie centrale 3 comprend au moins une zone faiblement comprimée 9 où la couche de mousse 6 présente une épaisseur supérieure ou égale à 12 mm, étant notamment comprise entre 15 et 30 mm.According to the embodiment shown, the central portion 3 comprises at least one weakly compressed zone 9 where the foam layer 6 has a thickness greater than or equal to 12 mm, being in particular between 15 and 30 mm.

Selon une réalisation, la couche fibreuse 5 présente en zone faiblement comprimée 9 une épaisseur supérieure ou égale à 4 mm, ladite épaisseur pouvant notamment aller jusqu'à 12 mm, de sorte que ladite couche fibreuse puisse présenter des propriétés d'absorption acoustique liées à sa porosité.According to one embodiment, the fibrous layer 5 has a thickness of greater than or equal to 4 mm in a weakly compressed zone 9, said thickness possibly being up to 12 mm, so that said fibrous layer may have sound absorption properties related to its porosity.

Une telle épaisseur peut notamment être atteinte par l'utilisation d'une couche fibreuse 5 de type « feutre gonflant ». Un tel feutre est fortement compressé lors de sa fabrication, pendant une étape de laminage, de manière à mettre les fibres en contrainte au sein du liant.Such a thickness can in particular be achieved by the use of a fibrous layer 5 of "swelling felt" type. Such a felt is strongly compressed during its manufacture, during a rolling step, so as to put the fibers in stress within the binder.

Lors du chauffage du feutre à température de fusion du liant, les fibres reprennent leur forme à l'état non contraint et ledit feutre gonfle de façon importante, ce qui permet de disposer, sur le panneau 1, d'au moins une zone faiblement comprimée 9 dans laquelle la couche fibreuse 5 présente une épaisseur telle que sus-décrite, qui permet de conférer à ladite couche fibreuse, dans ladite zone, des propriétés d'absorption acoustique se cumulant à celles apportées par la couche de mousse 6. Dans un tel feutre, la couche fibreuse 5 présente notamment les caractéristiques suivantes : - le liant thermoplastique est à base de polypropylène, - le taux de fibres est compris entre 40 et 60 % en poids, et notamment entre 45 et 55 % en poids, - les fibres ont une longueur minimale de 3 mm.When heating the felting agent at the binder's melting temperature, the fibers return to their unconstrained state and said felt swells considerably, which makes it possible to have on the panel 1 at least one weakly compressed zone. 9 in which the fibrous layer 5 has a thickness as described above, which makes it possible to impart to said fibrous layer, in said zone, sound absorption properties that accumulate with those provided by the foam layer 6. felt, the fibrous layer 5 has in particular the following characteristics: the thermoplastic binder is based on polypropylene, the fiber content is between 40 and 60% by weight, and especially between 45 and 55% by weight; have a minimum length of 3 mm.

Selon la réalisation représentée, la partie centrale 3 comprend au moins une zone de renfort 12 où la couche de mousse 6 est fortement comprimée, de manière à présenter une épaisseur résiduelle inférieure ou égale à 0,5 mm - étant notamment inférieure ou égale à 0,2 mm -, de sorte que l'épaisseur de l'âme 2 en ladite zone soit essentiellement constituée par l'épaisseur de ladite couche fibreuse.According to the embodiment shown, the central portion 3 comprises at least one reinforcing zone 12 where the foam layer 6 is strongly compressed, so as to have a residual thickness less than or equal to 0.5 mm - being in particular less than or equal to 0 , 2 mm -, so that the thickness of the core 2 in said zone is essentially constituted by the thickness of said fibrous layer.

Selon la réalisation représentée, le panneau comprend un insert 13 de renfort, notamment métallique, disposé entre la couche fibreuse 5 et la couche de mousse 6. Un tel insert 13 est notamment prévu dans le cas d'un panneau 1 sous forme d'une tablette de recouvrement d'un compartiment à bagages, ladite tablette n'étant pas destinée à être posée sur une tôle et devant présenter, de ce fait, une résistance importante à la flexion. Selon une réalisation, la couche fibreuse 5 présente une masse surfacique comprise entre 1200 et 1800 g/m2.According to an embodiment not shown, the panel 1 may comprise a functional member made of thermoplastic material welded upside down of a reinforcing zone 12. Such a member is for example - in the case of a panel 1 in the form of a tablet intended to be placed on a cover plate of the luggage compartment of the vehicle - a support foot or a fastening clip on said sheet. According to the embodiment shown, the panel comprises a reinforcing insert 13, in particular a metal insert, placed between the fibrous layer 5 and the foam layer 6. Such an insert 13 is in particular provided in the case of a panel 1 in the form of a covering tablet of a luggage compartment, said tablet not being intended to be placed on a sheet and thus having a high resistance to bending. According to one embodiment, the fibrous layer 5 has a density of between 1200 and 1800 g / m2.

Selon une réalisation, la couche fibreuse 5 comprend des billes expansées. La présence de telles billes permet d'obtenir une expansion accentuée de la couche fibreuse 5, améliorant ses propriétés d'absorption acoustique.In one embodiment, the fibrous layer 5 comprises expanded beads. The presence of such beads makes it possible to obtain an increased expansion of the fibrous layer 5, improving its acoustic absorption properties.

Selon une réalisation, la partie périphérique 4 présente une largeur développée 14 comprise entre 20 et 50 mm.According to one embodiment, the peripheral portion 4 has a developed width 14 of between 20 and 50 mm.

Selon une réalisation, la partie périphérique 4 s'étend sur toute la périphérie de l'âme 2. On décrit enfin un procédé de réalisation d'un tel panneau 1, ledit procédé comprenant les étapes suivantes : - superposer, dans un moule de thermocompression conformé à la géométrie du panneau 1 à obtenir, une couche de revêtement d'endroit 7, une couche fibreuse 5 à base de fibres de verre liées entre elles par un liant thermoplastique, une couche de mousse de polyuréthanne 6 et une couche de revêtement d'envers 8, de manière à définir un multicouches, - réaliser une thermocompression dudit multicouches, de manière à conformer lesdites couches, et une découpe périphérique, ladite découpe étant notamment réalisée simultanément avec la thermocompression, ladite découpe étant réalisée de sorte que lesdites couches de revêtement se rejoignent bord à bord selon une ligne de jonction 10, de manière à masquer la tranche 11 de l'âme 2 formée par lesdites couche fibreuse et de mousse, lesdites couches de revêtement étant tranchées au raz de ladite tranche et de ladite ligne.According to one embodiment, the peripheral portion 4 extends over the entire periphery of the core 2. Finally, a method of producing such a panel 1 is described, said method comprising the following steps: superimposing, in a thermocompression mold according to the geometry of the panel 1 to be obtained, a location coating layer 7, a fibrous layer 5 based on glass fibers bonded together by a thermoplastic binder, a layer of polyurethane foam 6 and a coating layer of 8, in order to define a multilayer, - thermocompression of said multilayer, so as to conform said layers, and a peripheral cut, said cut being in particular performed simultaneously with the thermocompression, said cut being made so that said layers of coating join edge to edge along a junction line 10, so as to hide the edge 11 of the core 2 formed by said fibrous layer and foam, said coating layers being sliced off said slice and said line.

Pour obtenir la couche de mousse 6, on peut notamment partir d'une plaque de mousse semi-rigide thermo-formable de faible densité - notamment de l'ordre de 0,015 - et de haute tortuosité, ce qui lui confère de très bonnes propriétés d'absorption acoustique.In order to obtain the foam layer 6, it is possible in particular to start from a low-density thermoformable semi-rigid foam plate - in particular of the order of 0.015 - and of high tortuosity, which gives it very good properties. sound absorption.

Selon une réalisation, la plaque de mousse avant thermo-compression présente une épaisseur comprise entre 10 et 20 mm.
