Description
La présente invention concerne un panneau avec fonction coupe-feu destiné à être utilisé dans tout type de véhicule transportant des passagers.The present invention relates to a panel with a fire barrier function intended to be used in any type of vehicle transporting passengers.
Les normes EN50553 de septembre 2012 (capacité à rouler avec un feu à bord) et EN45545-3 d’avril 2013 (barrière au feu) imposent de protéger les fonctions principales d’un véhicule transportant des passagers, notamment véhicule ferroviaire, dans le cas d’éventuels incendies, notamment les feux de bagages. Ces fonctions doivent être maintenues pendant une durée évoluant selon le type de matériel roulant et l’infrastructure associée. La fonction coupe-feu doit être réalisée dans un volume restreint au maximum avec une masse la plus faible possible, pour des raisons de volumes disponibles et de masse restreinte (l’infrastructure limitant les masses à l’essieu des trains en roulement). Les fonctions principales à protéger peuvent être de tout type et notamment les équipements électriques tels que les armoires électriques, par exemple les armoires basse tension (ABT).Standards EN50553 of September 2012 (ability to drive with a light on board) and EN45545-3 of April 2013 (barrier to fire) require protection of the main functions of a vehicle transporting passengers, in particular a railway vehicle, in the case possible fires, in particular luggage fires. These functions must be maintained for a period that varies according to the type of rolling stock and the associated infrastructure. The firebreak function must be performed in a volume restricted to the maximum with the lowest possible mass, for reasons of available volumes and limited mass (the infrastructure limiting the masses at the axle of running gear). The main functions to be protected can be of any type and in particular electrical equipment such as electrical cabinets, for example low voltage cabinets (ABT).
Il est connu des panneaux comprenant une couche barrière isolante de type laine de roche, laine de verre ou laine de silice et une couche d’étanchéité au feu de type tôle métallique. Cependant, ces deux fonctions empilées augmentent le volume et la masse de la paroi.Panels comprising an insulating barrier layer of the rock wool, glass wool or silica wool type and a fireproofing layer of the metal sheet type are known. However, these two stacked features increase the volume and mass of the wall.
Il existe donc un intérêt de fournir un panneau avec fonction coupe-feu de volume et masse restreints.There is therefore an interest in providing a panel with a firebreak function of limited volume and mass.
A cet effet, l’invention a pour objet un panneau comprenant :To this end, the subject of the invention is a panel comprising:
- un matériau ablatif ;an ablative material;
- sur l’une des faces du matériau ablatif un film décoratif ;on one side of the ablative material a decorative film;
- sur l’autre face du matériau ablatif une couche métallique d’une épaisseur comprise entre 0,8 mm et 5 mm.on the other side of the ablative material a metal layer with a thickness between 0.8 mm and 5 mm.
Le matériau ablatif est donc pris en sandwich entre le film décoratif et la couche métallique.The ablative material is therefore sandwiched between the decorative film and the metallic layer.
Dans le cadre de la présente invention, on entend par matériau ablatif un matériau susceptible de se sublimer sous l’effet d’une chaleur intense. Ainsi, un matériau ablatif élimine la chaleur en se décomposant couche par couche. La décomposition de ces matériaux ablatifs est contrôlée et permet donc d’évaluer avec précision la proportion de matériau décomposé dans un temps donné. Il est ainsi possible de prévoir l’épaisseur de matériau nécessaire selon les requis de temps de tenue et d’isolation au feu.In the context of the present invention, the term “ablative material” means a material capable of sublimating under the effect of intense heat. Thus, an ablative material removes heat by breaking down layer by layer. The decomposition of these ablative materials is controlled and therefore makes it possible to accurately assess the proportion of material decomposed in a given time. It is thus possible to predict the thickness of material required according to the required fire resistance and insulation time.
De préférence, l’épaisseur du matériau ablatif se détermine en fonction des requis de temps de tenue et d’isolation au feu. L’objectif est de limiter l’épaisseur de ce matériau pour limiter la masse et le volume. Par exemple, pour une épaisseur de 14.5mm (mêmes performances au feu que la solution décrite ci-dessus avec la laine de roche, laine de verre ou laine de silice), la masse surfacique est de 7,7kg/m² soit une réduction de masse de 50%. L’épaisseur du matériau ablatif est de préférence comprise entre 5 mm et 50 mm, de préférence entre 10 et 13,5 mm.Preferably, the thickness of the ablative material is determined according to the resistance time and fire insulation requirements. The objective is to limit the thickness of this material to limit the mass and the volume. For example, for a thickness of 14.5mm (same fire performance as the solution described above with rock wool, glass wool or silica wool), the surface mass is 7.7 kg/m², i.e. a reduction of 50% mass. The thickness of the ablative material is preferably between 5 mm and 50 mm, preferably between 10 and 13.5 mm.
Le matériau ablatif est de préférence choisi parmi la famille des lièges, par exemple Norcoat® Liège.The ablative material is preferably chosen from the cork family, for example Norcoat® Liège.
La couche métallique (ou couche de matériau métallique) peut se présenter sous la forme d’une tôle métallique. De préférence, le métal est l’aluminium, et la couche métallique est de préférence une tôle d’aluminium.The metal layer (or layer of metallic material) may be in the form of a metal sheet. Preferably, the metal is aluminum, and the metal layer is preferably an aluminum sheet.
De préférence, la couche métallique présente une épaisseur comprise entre 0,8 et 5 mm. Cette épaisseur dépend notamment du métal mis en œuvre.Preferably, the metal layer has a thickness of between 0.8 and 5 mm. This thickness depends in particular on the metal used.
Le film décoratif présente de préférence une épaisseur comprise entre 0,5 et 6 mm, de préférence entre 0,6 et 1,2 mm.The decorative film preferably has a thickness of between 0.5 and 6 mm, preferably between 0.6 and 1.2 mm.
Dans le panneau de l’invention, le film décoratif (ou couche de décor) peut être lié au matériau ablatif à l’aide d’un adhésif. Ainsi, de préférence le film décoratif est adhésivé sur l’une des faces du matériau ablatif.In the panel of the invention, the decorative film (or decorative layer) can be bonded to the ablative material using an adhesive. Thus, preferably the decorative film is adhesive-coated on one of the faces of the ablative material.
Dans le panneau de l’invention, la couche métallique peut être collée sur la seconde face du matériau ablatif ou bien liée de façon mécanique. Dans ce dernier cas, par exemple, le panneau en matériau ablatif peut être contenu dans une ossature métallique avec rebords ou bien le panneau de matériau ablatif est vissé sur un cadre métallique avec la couche métallique en sandwich.In the panel of the invention, the metal layer can be glued to the second face of the ablative material or even bonded mechanically. In the latter case, for example, the panel made of ablative material can be contained in a metal framework with flanges or else the panel of ablative material is screwed onto a metal frame with the metal layer in a sandwich.
L’invention a également pour objet un véhicule comportant un panneau selon l’invention, notamment pour la protection des fonctions principales du véhicule, par exemple équipement électrique tel qu’armoire électrique (par exemple armoire basse tension), dans le cas d’éventuels incendies.The invention also relates to a vehicle comprising a panel according to the invention, in particular for the protection of the main functions of the vehicle, for example electrical equipment such as an electrical cabinet (for example low voltage cabinet), in the case of possible fires.
Le véhicule peut être tout type de véhicule transportant des passagers, par exemple véhicules ferroviaires (train, métro), bus, bateaux, avions, etc. De préférence le véhicule est un véhicule ferroviaire.The vehicle can be any type of vehicle carrying passengers, for example railway vehicles (train, metro), buses, ships, planes, etc. Preferably the vehicle is a railway vehicle.
L’invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d’exemple, non limitatif, et faite en se référant aux dessins annexés sur lesquels :The invention will be better understood on reading the description which follows, given solely by way of example, not limiting, and made with reference to the appended drawings in which:

Le matériau ablatif 2 est donc pris en sandwich entre le film décoratif 1 et la couche métallique 3.The ablative material 2 is therefore sandwiched between the decorative film 1 and the metal layer 3.
Le matériau ablatif 2 a la propriété d’éliminer la chaleur en se décomposant couche par couche. La décomposition de ce matériaux ablatif 2 est contrôlée et permet donc d’évaluer avec précision la proportion de matériau décomposé dans un temps donné. Il est ainsi possible de prévoir l’épaisseur de matériau ablatif nécessaire selon les requis de temps de tenue et d’isolation au feu.The ablative material 2 has the property of eliminating heat by breaking down layer by layer. The decomposition of this ablative material 2 is controlled and therefore makes it possible to accurately evaluate the proportion of material decomposed in a given time. It is thus possible to predict the thickness of ablative material required according to the required resistance time and fire insulation.
De préférence, l’épaisseur du matériau ablatif 2 se détermine en fonction des requis de temps de tenue et d’isolation au feu. L’objectif est de limiter l’épaisseur de ce matériau pour limiter la masse et le volume. Par exemple, pour une épaisseur de 14.5mm (mêmes performances au feu que la solution décrite ci-dessus avec la laine de roche, laine de verre ou laine de silice), la masse surfacique est de 7.7kg/m² soit une réduction de masse de 50%. L’épaisseur du matériau ablatif 2 est de préférence comprise entre 5 et 50 mm, de préférence entre 10 et 13,5 mm.Preferably, the thickness of the ablative material 2 is determined according to the resistance time and fire insulation requirements. The objective is to limit the thickness of this material to limit the mass and the volume. For example, for a thickness of 14.5mm (same fire performance as the solution described above with rock wool, glass wool or silica wool), the surface mass is 7.7kg/m², i.e. a mass reduction by 50%. The thickness of the ablative material 2 is preferably between 5 and 50 mm, preferably between 10 and 13.5 mm.
Le matériau ablatif 2 est de préférence choisi parmi la famille des lièges, par exemple Norcoat® Liège.The ablative material 2 is preferably chosen from the cork family, for example Norcoat® Liège.
La couche métallique 3 peut se présenter sous la forme d’une tôle aluminium.The metal layer 3 can be in the form of an aluminum sheet.
De préférence, la couche métallique 3 présente une épaisseur comprise entre 0,8 et 5 mm.Preferably, the metal layer 3 has a thickness of between 0.8 and 5 mm.
Le film décoratif 1 présente de préférence une épaisseur comprise entre 0,5 et 6 mmm, de préférence entre 0,6 et 1,2 mm.The decorative film 1 preferably has a thickness of between 0.5 and 6 mmm, preferably between 0.6 and 1.2 mm.

Le panneau ainsi constitué de l’invention assure une fonction cloison tout au long du fonctionnement du véhicule. Il permet ainsi de former cloison entre les fonctions à protéger (notamment équipement électrique, par exemple armoire électrique telle qu’armoire basse tension (ABT)) et la salle du véhicule. Lors d’un incendie, par exemple incendie de bagage, le film décoratif 1 brule et le matériau ablatif 2 consomme l’énergie de l’incendie en se dégradant et en laissant intacte la couche métallique 3 permettant ainsi une protection optimale des fonctions à protéger.The panel thus constituted by the invention performs a partition function throughout the operation of the vehicle. It thus makes it possible to form a partition between the functions to be protected (in particular electrical equipment, for example electrical cabinet such as low voltage cabinet (ABT)) and the vehicle room. During a fire, for example a luggage fire, the decorative film 1 burns and the ablative material 2 consumes the energy of the fire by degrading and leaving the metal layer 3 intact, thus allowing optimal protection of the functions to be protected. .
