Definitions

  • the invention relates to a laminate comprising a skin plate made from steel and a shaped layer, which shaped layer is joined to the skin plate and forms cavities and/or passages with the skin plate, which passages and/or cavities are optionally connected to one another.
  • Laminates of this type are known and are used for a wide range of applications, optionally also having been provided with a second skin plate so as to form a sandwich material.
  • An important object of a sandwich material or laminate is usually to provide a lightweight plate which is also strong.
  • sandwich materials are suitable for this purpose, since the core between the skin plates of a sandwich of this type can be produced from a lightweight material, while the (thin) skin plates together provide the strength.
  • honeycomb material which is used in catalytic converters for vehicles.
  • This material usually comprises one flat and one corrugated metal sheet, which are joined to one another, for example by soldering or brazing, with the laminate being rolled up in order to produce a catalytic converter with a large reactive surface area.
  • Catalytic converters for vehicles have to be able to withstand high temperatures.
  • a sandwich material comprising honeycomb material in the true sense of the word is also known; in this case, honeycomb core material is accommodated between skin plates, with the walls of the honeycomb core material perpendicular to the skin plates.
  • Honeycomb sandwiches of this type are known in a fully paper design or as paper core material between wooden panels; these sandwiches are relative inexpensive.
  • a laminate comprising a skin plate made from steel and a shaped layer, which skin plate has an outwardly facing side and a side which faces towards the shaped layer, and which shaped layer has a side facing towards the skin plate and an outwardly facing side, in which the shaped layer substantially consists of a shaped steel plate, which shaped layer is joined to the skin plate and 5 forms passages and/or cavities together with the skin plate, which passages and/or cavities are optionally connected to one another, and in which a polymer material creates the bonding between the skin plate and the shaped layer.
  • Bonding the skin plate to the shaped layer with the aid of a polymer material creates a very simple joining technique for joining the metal skin plate and the0 shaped layer to one another.
  • polymer material has a softening range when it is heated, the joining is easy to carry out by heating the polymer material at least at the contact surfaces between the skin plate and the shaped layer.
  • the shaped layer leaves opens passages and/or cavities, it is possible to use these passages and/or cavities for5 design purposes, while the weight of the laminate also remains as low as possible, on account of the shaped layer not being solid.
  • both plates are provided with a layer of polymer material on their inner side, since this produces excellent bonding and the passages and/or cavities between the two steel plates are completely surrounded by polymer material, so that there is no5 risk of rust forming on the steel plates.
  • the skin plate from stainless steel; in this case, a layer of polymer material on the shaped steel plate is sufficient to prevent the formation of rust. It is preferable for the outwardly facing side of the skin plate and the outwardly facing side of the shaped layer to be provided with a layer of polymer0 material. As a result, the outer sides of the laminate are protected against the formation of rust. It is also possible for the skin plate to be printed on or for the layer of polymer material to be coloured. According to a preferred embodiment, a second skin plate is joined to the shaped layer in order to form a sandwich material. The second skin plate is also5 bonded to the shaped layer with the aid of the polymer material. As a result, the . sandwich material is substantially just as easy to produce as the laminate as ' . ;. discussed above.
  • the shaped layer with the second skin plate likewise to form passages and/or cavities, which passages and/or cavities are optionally connected to one another. It is therefore possible, for example, to create a sandwich material which has passages and/or cavities on both sides of the shaped layer.
  • both sides of the steel shaped layer and/or the inwardly facing sides of the skin plates to be provided with a layer of polymer material. This gives rise, mutatis mutandis, to the same advantages as for the laminate.
  • the outwardly facing sides of the skin plates to be provided with a layer of polymer material. The same advantage applies here as for the laminate.
  • the skin plate or plates are between 0.05 and 0.6 mm thick, preferably between 0.05 and 0.3 mm thick.
  • Using steel skin plates of this thickness produces a laminate or sandwich of a very low weight, while the laminate or sandwich is nevertheless strong, on account of the use of the steel skin plates.
  • the steel skin plate also has a good resistance to damage and the like.
  • the material of the shaped layer it is preferable for the material of the shaped layer to be between 0.05 and 0.6 mm thick. Such a thickness of the shaped layer made from steel is enough to achieve a sufficient strength and rigidity.
  • the layer of polymer material on the steel skin plate or plates and/or the steel shaped layer is between 0.015 mm and
  • the passages in the laminate or the sandwich material are designed in such a way that the passages in the laminate can be used as one or more lines for transporting a fluid.
  • passages and/or cavities in the laminate are filled with an energy-absorbing material.
  • the laminate or sandwich material may then, for example, be used in the construction industry as an energy-absorbing material in, for example, walls, in order to attenuate the daily temperature change in the building.
  • cavities in the laminate are closed, and these cavities are under a pressure which is lower than atmospheric pressure.
  • the laminate or sandwich material has a insulating property. It is preferable for the laminate or sandwich material to be between 1 mm and 100 mm thick, preferably between 2 mm and 40 mm thick. These thicknesses are readily useable in all kinds of applications, such as in the construction industry, in shipbuilding and in the automotive industry, but the lower thicknesses can also be used, for example, in the packaging industry and the production of equipment.
  • a second aspect of the invention provides a method for producing laminate or sandwich material as described above, in which the skin plate or plates and the shaped layer are brought into contact with one another and the bonding between the skin plate or plates and the shaped layer is brought about by heating the polymer material.
  • This method creates the bonding between skin plate or plates and shaped layer in a simple and inexpensive way.
  • the heating is preferably realized with the aid of induction heating or with the aid of radiant heat. These ways of supplying heat can be used in a simple and inexpensive way on an industrial scale. Induction heating is possible on account of the fact that the skin plate or plates are made from steel.
  • the laminate (or sandwich material) is produced substantially continuously.
  • the laminate produced may if appropriate be coiled or processed to form plates; sandwich material produced will have to be processed to form plates.
  • the steel shaped layer it is preferable for the steel shaped layer to be shaped substantially continuously before being brought into contact with and bonded to the skin plate or plates. This allows the laminate or sandwich material to be produced continuously by supplying two or three steel strips from a coil and shaping one of them, so that the strips can be bonded to one another by heating. One or more of these strips will usually be provided with a layer of polymer material on one or both sides, although it is also possible for the layer of polymer material to be supplied as separate strip.

Abstract

L'invention concerne un stratifié comprenant une plaque de peau en acier et une couche façonnée. La plaque de peau possède un côté tourné vers l'extérieur et un côté tourné vers la couche façonnée, laquelle possède un côté tourné vers la plaque de peau et un côté tourné vers l'extérieur. Selon l'invention, la couche façonnée consiste sensiblement en une tôle d'acier, est liée à la plaque de peau et forme des passages et/ou des cavités conjointement avec la plaque de peau, passages et/ou cavités éventuellement reliés les uns aux autres, et une matière polymère crée une liaison entre la plaque de peau et la couche façonnée. Selon l'invention, le stratifié peut être doté d'une seconde plaque de peau de manière qu'un matériau en sandwich soit formé.
