L'invention concerne un matériau multicouche (100, 150) comportant : - une âme (102) en nid d'abeilles, - deux feuilles réflectives (106a-b) collées de part et d'autre de l'âme (102) et - deux feuilles de carton (108a-b) collées sur les faces des feuilles réflectives (106a-b) qui sont orientées à l'opposé de l'âme (102).The invention relates to a multilayer material (100, 150) comprising: - a core (102) honeycomb, - two reflective sheets (106a-b) bonded on both sides of the core (102) and - two sheets of cardboard (108a-b) glued on the faces of the reflective sheets (106a-b) which are oriented opposite the core (102).

Description

La présente invention concerne un matériau multicouche à base de nid d’abeilles ainsi qu’un système multicouche comportant un tel matériau.The present invention relates to a multilayer material based on honeycomb and a multilayer system comprising such a material.

On connaît un matériau multicouche sous la forme d’un panneau qui comporte une âme en nid d’abeilles. La structure en nid d’abeilles prend la forme d’alvéoles délimitées par des parois orientées selon une direction perpendiculaire au plan du panneau. De part et d’autre de l’âme est collée une feuille de carton orientée parallèlement au plan du panneau et sur chacune des faces des feuilles en carton qui sont orientées à l’opposé de l’âme est collée une feuille réflective comme une feuille en aluminium.A multilayer material is known in the form of a panel which comprises a honeycomb core. The honeycomb structure takes the form of cells delimited by walls oriented in a direction perpendicular to the plane of the panel. On both sides of the core is glued a sheet of cardboard oriented parallel to the plane of the panel and on each side of the cardboard sheets which are oriented opposite the core is glued a reflective sheet like a sheet in aluminium.

Bien qu’un tel matériau multicouche donne satisfaction du point de vue de l’isolation thermique, il peut dans certains cas présenter des inconvénients.Although such a multilayer material is satisfactory from the point of view of thermal insulation, it can in some cases have disadvantages.

Par exemple, lorsqu’un tel matériau est utilisé pour isoler un mur, l’application de la feuille réflective contre le mur réduit fortement, voire annule, la capacité réflective de la feuille.For example, when such a material is used to insulate a wall, the application of the reflective sheet against the wall greatly reduces or cancels the reflective capacity of the sheet.

Par exemple, lorsqu’un tel matériau est utilisé pour réaliser une caisse de transport, la feuille réflective orientée vers l’extérieur peut être abîmée durant le transport ou en contact avec une autre paroi et la feuille réflective orientée vers l’intérieur peut être en contact avec la marchandise.For example, when such a material is used to make a transport case, the outwardly oriented reflective sheet may be damaged during transport or in contact with another wall and the inwardly oriented reflective sheet may be exposed. contact with the goods.

Un objet de la présente invention est de proposer un matériau multicouche à base de nid d’abeilles qui ne présente pas les inconvénients de l'art antérieur. A cet effet, est proposé un matériau multicouche comportant : - une âme en nid d’abeilles, - deux feuilles réflectives collées de part et d’autre de l’âme et - deux feuilles de carton collées sur les faces des feuilles réflectives qui sont orientées à l’opposé de l’âme.An object of the present invention is to provide a multilayer honeycomb material which does not have the drawbacks of the prior art. For this purpose, is proposed a multilayer material comprising: - a honeycomb core, - two reflective sheets bonded on both sides of the core and - two sheets of cardboard glued to the faces of the reflective sheets which are oriented away from the soul.

Avantageusement, le matériau multicouche comporte une feuille réflective collée sur la face de l’une des feuilles en carton qui est orientée à l’opposé de l’âme.Advantageously, the multilayer material comprises a reflective sheet bonded to the face of one of the cardboard sheets which is oriented away from the core.

Avantageusement, le matériau multicouche comporte une feuille réflective collée sur les faces des deux feuilles en carton qui sont orientées à l’opposé de l’âme. L’invention propose également un système multicouche comportant un noyau sous forme d’un panneau et un matériau multicouche selon le mode de réalisation précédent de part et d’autre du noyau, chaque matériau multicouche étant collé contre une face du noyau par l’intermédiaire de l’une de ces feuilles de carton. L’invention propose également un système multicouche comportant un noyau sous forme d’un panneau, et collée de part et d’autre du noyau, une feuille réflective, et collé sur l’extérieur de chaque feuille réflective, un matériau multicouche selon le mode de réalisation précédent. L’invention propose également un système multicouche comportant deux matériaux multicouche selon le mode de réalisation précédent, chaque matériau multicouche étant collé à l’autre matériau multicouche par l’intermédiaire de l’une de ces feuilles de carton.Advantageously, the multilayer material comprises a reflective sheet bonded to the faces of the two cardboard sheets which are oriented opposite the core. The invention also proposes a multilayer system comprising a core in the form of a panel and a multilayer material according to the preceding embodiment on either side of the core, each multilayer material being bonded against one face of the core via from one of these cardboard sheets. The invention also proposes a multilayer system comprising a core in the form of a panel, and bonded on either side of the core, a reflective sheet, and adhered to the outside of each reflective sheet, a multilayer material depending on the mode. previous realization. The invention also proposes a multilayer system comprising two multilayer materials according to the preceding embodiment, each multilayer material being bonded to the other multilayer material by means of one of these sheets of cardboard.

Selon un mode de réalisation particulier, le système multicouche comporte une feuille réflective collée sur la face de l’une des feuilles en carton qui est orientée vers l’extérieur.According to a particular embodiment, the multilayer system comprises a reflective sheet bonded to the face of one of the cardboard sheets which faces outwards.

Selon un mode de réalisation particulier, le système multicouche comporte une feuille réflective collée sur les faces des deux feuilles en carton qui sont orientées vers l’extérieur.According to a particular embodiment, the multilayer system comprises a reflective sheet bonded to the faces of the two cardboard sheets which are oriented towards the outside.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels : la Fig. 1 est une vue en coupe d’un matériau multicouche à base de nid d’abeilles selon l’invention, la Fig. 2 est une vue en coupe d’un système multicouche à base du matériau de la Fig. 1 selon un premier mode de réalisation, la Fig. 3 est une vue en coupe d’un système multicouche à base du matériau de la Fig. 1 selon un deuxième mode de réalisation, et la Fig. 4 est une vue en coupe d’un système multicouche à base du matériau de la Fig. 1 selon un troisième mode de réalisation.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in connection with the attached drawings, among which: FIG. . 1 is a sectional view of a multilayer honeycomb material according to the invention, FIG. 2 is a sectional view of a multilayer system based on the material of FIG. 1 according to a first embodiment, FIG. 3 is a sectional view of a multilayer system based on the material of FIG. 1 according to a second embodiment, and FIG. 4 is a sectional view of a multilayer system based on the material of FIG. 1 according to a third embodiment.

La partie gauche de la Fig. 1 montre un matériau multicouche 100 sous forme d’un panneau qui comprend une âme 102 en nid d’abeilles qui forme une structure alvéolaire où chaque alvéole 104 est délimitée par des parois 105 qui sont orientées selon une même direction 10 qui est perpendiculaire au plan du panneau.The left part of FIG. 1 shows a multilayer material 100 in the form of a panel which comprises a honeycomb core 102 which forms a honeycomb structure where each cell 104 is delimited by walls 105 which are oriented in the same direction 10 which is perpendicular to the plane of the panel.

De part et d’autre de l’âme 102 est collée une feuille réflective 106a-b présentant un fort facteur de réflexion orientée parallèlement au plan du panneau et sur chacune des faces des feuilles réflécrives 106a-b qui sont orientées à l’opposé de l’âme 102 est collée une feuille de carton 108a-b. Chaque feuille réflective 106a-b est par exemple une feuille d’aluminium.On either side of the core 102 is glued a reflective sheet 106a-b having a high reflection factor oriented parallel to the plane of the panel and on each of the faces of the reflective sheets 106a-b which are oriented opposite the the core 102 is glued a sheet of cardboard 108a-b. Each reflective sheet 106a-b is for example an aluminum foil.

Un tel matériau multicouche 100 présente des caractéristiques d’isolation thermique similaires à celles du matériau de l’état de la technique, mais la position des feuilles réflectives 106a-b à l’intérieur du panneau évite les inconvénients mentionnés ci-dessus, et limite surtout le transfert de température depuis l’intérieur de l’âme 102.Such a multilayer material 100 has thermal insulation characteristics similar to those of the material of the state of the art, but the position of the reflective sheets 106a-b inside the panel avoids the disadvantages mentioned above, and limits especially the temperature transfer from the inside of the soul 102.

Chaque feuille réflective 106a-b est ainsi collée directement sur l’âme 102 au niveau des tranches de chaque paroi 105.Each reflective sheet 106a-b is thus glued directly on the core 102 at the edges of each wall 105.

La partie droite de la Fig. 1 montre un matériau multicouche 150 qui comprend les mêmes éléments que ceux du matériau multicouche 100 de la partie gauche et qui comporte également, pour renforcer sa capacité thermique, une feuille réflective 110a-b collée sur la face de l’une des feuilles en carton 108a-b qui est orientée à l’opposé de l’âme 102 ou sur les faces des deux feuilles en carton 108a-b qui sont orientées à l’opposé de l’âme 102. Chaque feuille réflective llOa-b est par exemple une feuille d’aluminium.The right part of FIG. 1 shows a multilayer material 150 which comprises the same elements as those of the multilayer material 100 of the left part and which also comprises, to enhance its thermal capacity, a reflective sheet 110a-b bonded to the face of one of the cardboard sheets 108a-b which is oriented opposite the web 102 or on the faces of the two cardboard sheets 108a-b which are oriented opposite the web 102. Each reflective sheet 110a-b is for example a aluminum foil.

Dans le mode de réalisation de l’invention présenté sur la partie droite de la Fig. 1, il y a une feuille réflective 1 lOa-b sur les deux faces extérieures du panneau, c'est-à-dire sur les deux faces orientées à l’opposé de l’âme 102.In the embodiment of the invention shown on the right side of FIG. 1, there is a reflective sheet 1 10a-b on the two outer faces of the panel, that is to say on both sides facing away from the core 102.

La Fig. 2 et la Fig. 3 montrent des systèmes multicouches 200, 250, 300 et 350 qui comportent chacun un noyau 202, 302 en matériau isolant sous forme d’un panneau et des structures en nid d’abeilles qui permettent de créer un renfort structurel pour le noyau 202, 302. Le noyau 202, 302 se présente sous la forme d’un panneau épais.Fig. 2 and FIG. 3 show multilayer systems 200, 250, 300 and 350 which each comprise a core 202, 302 of insulating material in the form of a panel and honeycomb structures which make it possible to create a structural reinforcement for the core 202, 302 The core 202, 302 is in the form of a thick panel.

La partie gauche de la Fig. 2 montre un système multicouche 200 qui comporte le noyau 202 en matériau isolant sous forme d’un panneau et de part et d’autre du noyau 202, un matériau multicouche 100 selon le mode de réalisation de la partie gauche de la Fig. 1. Chaque matériau multicouche 100 est collé contre une face du noyau 202 par l’intermédiaire de l’une de ces feuilles de carton, ici 108a. Ce mode de réalisation est plus particulièrement mis en œuvre lorsque le matériau isolant constituant le noyau 202 présente une porosité peu importante lorsque le matériau isolant est dense comme par exemple dans le cas du polyuréthane de forte densité ou d’un aggloméré de fibres.The left part of FIG. 2 shows a multilayer system 200 which comprises the core 202 of insulating material in the form of a panel and on either side of the core 202, a multilayer material 100 according to the embodiment of the left part of FIG. 1. Each multilayer material 100 is bonded to one face of the core 202 through one of these sheets of paperboard, here 108a. This embodiment is more particularly implemented when the insulating material constituting the core 202 has a low porosity when the insulating material is dense, as for example in the case of high density polyurethane or an agglomerate of fibers.

La partie droite de la Fig. 2 montre un système multicouche 250 qui comprend les mêmes éléments que ceux du système multicouche 200 de la partie gauche et qui comporte également, pour renforcer sa capacité thermique, une feuille réflective 210a-b collée sur la face de l’une des feuilles en carton, ici 108b, qui est orientée vers l’extérieur, c'est-à-dire qui n’est pas collée au noyau 202, ou sur les faces des deux feuilles en carton, ici 108b, qui sont orientées vers l’extérieur. Chaque feuille réflective 210a-b est par exemple une feuille d’aluminium.The right part of FIG. 2 shows a multilayer system 250 which comprises the same elements as those of the multilayer system 200 of the left part and which also comprises, to enhance its thermal capacity, a reflective sheet 210a-b bonded to the face of one of the cardboard sheets here 108b, which is outwardly oriented, that is to say which is not glued to the core 202, or on the faces of the two cardboard sheets, here 108b, which are oriented outwards. Each reflective sheet 210a-b is for example an aluminum foil.

Dans le mode de réalisation de l’invention présenté sur la partie droite de la Fig. 2, il y a une feuille réflective 210a-b sur les deux faces extérieures du système multicouche 250, c'est-à-dire sur les deux faces orientées vers l’extérieur.In the embodiment of the invention shown on the right side of FIG. 2, there is a reflective sheet 210a-b on the two outer faces of the multilayer system 250, i.e. on both outward facing faces.

La partie gauche de la Fig. 3 montre un système multicouche 300 qui comporte le noyau 302 en matériau isolant sous forme d’un panneau, et collée de part et d’autre du noyau 302, une feuille réflective 309a-b, et collé sur l’extérieur de chaque feuille réflective 309a-b, un matériau multicouche 100 selon le mode de réalisation de la partie gauche de la Fig. 1.The left part of FIG. 3 shows a multilayer system 300 which comprises the core 302 of insulating material in the form of a panel, and glued on either side of the core 302, a reflective sheet 309a-b, and adhered to the outside of each reflective sheet 309a-b, a multilayer material 100 according to the embodiment of the left part of FIG. 1.

Ce mode de réalisation est plus particulièrement mis en œuvre lorsque le matériau isolant constituant le noyau 302 présente une porosité importante comme lorsque le matériau isolant est de faible densité avec des bulles d’air, où le collage de la feuille réflective 309a-b ne réduit pas ses caractéristiques réflectrices. Le matériau isolant est par exemple du polyuréthane de faible densité ou un aggloméré de fibres de bois de faible densité.This embodiment is more particularly implemented when the insulating material constituting the core 302 has a high porosity as when the insulating material is of low density with air bubbles, where the bonding of the reflective sheet 309a-b reduces not its reflective characteristics. The insulating material is, for example, low density polyurethane or a low density wood fiber chip.
