Abstract
Description
La présente invention concerne la réalisation d'éléments de construction ou de décoration en céramique et a pour objet un procédé de stabilisation de plaques minces et fragiles en céramique pour la constitution de ces éléments.The present invention relates to the production of building or decorative elements in ceramic and relates to a method for stabilizing thin and fragile ceramic plates for the constitution of these elements.
Actuellement, il est possible d'obtenir des plaques minces en céramique d'épaisseur inférieure à 3,5 mm suivant un procédé d'élaboration de films de céramique par électrodé position. Ces films minces sont peu onéreux à fabriquer mais les plaques en résultant sont d'un emploi limité parce que trop fragiles.Currently, it is possible to obtain thin ceramic plates with a thickness of less than 3.5 mm according to a process for producing ceramic films by position electrode. These thin films are inexpensive to manufacture, but the resulting plates are of limited use because they are too fragile.
On connaît par le document US-A-3 723 233 un procédé de stabilisation de plaques en marbre minces et fragiles, qui consiste à monter lesdites plaques sur une structure portante constituée d'un matériau sandwich, dont le noyau est du type nid d'abeille.Document US-A-3 723 233 discloses a method for stabilizing thin and fragile marble slabs, which consists in mounting said slabs on a bearing structure made of a sandwich material, the core of which is of the nest type. bee.
Il a paru par suite avantageux suivant l'invention de créer un procédé de stabilisation consistant à monter les plaques minces en céramique sur une structure portante constituée d'un matériau sandwich, dont le noyau est du type nid d'abeille ou mousse synthétique et caractérisé en ce que la stabilisation des plaques minces et fragiles est obtenue par la participation directe du film de céramique à la constitution de la structure portante.It therefore appeared advantageous according to the invention to create a stabilization process consisting in mounting the thin ceramic plates on a bearing structure made of a sandwich material, the core of which is of the honeycomb or synthetic foam type and characterized in that the stabilization of the thin and fragile plates is obtained by the direct participation of the ceramic film in the constitution of the supporting structure.
Les composites ainsi formés, présentant les plaques de céramiques minces sur une ou les deux faces, confèrent au film de céramique des performances mécaniques élevées en flexion et au flambage.The composites thus formed, having the thin ceramic plates on one or both sides, give the ceramic film high mechanical performance in bending and buckling.
Le comportement au choc de ces composites constituant des panneaux en céramique, plats ou présentant des courbures, est modifié par rapport à des panneaux en céramique courants, les dégradations dues à un impact par exemple s'avérant être limitées à l'endroit dudit impact sans propagation des dommages aux alentours.The impact behavior of these composites constituting ceramic panels, flat or having curvatures, is modified compared to common ceramic panels, the degradations due to an impact for example proving to be limited at the location of said impact without spread of damage to the surroundings.
La fixation de ces plaques minces de céramique en composites suivant l'invention est beaucoup plus aisée par rapport aux panneaux en céramique courants qui ne présentent que très peu de résistance aux joints d'ancrage.The fixing of these thin ceramic composite plates according to the invention is much easier compared to current ceramic panels which have very little resistance to the anchoring joints.
En cas de montage de la plaque mince en céramique sur la structure portante, c'est principalement la structure portante qui déterminera les caractéristiques de l'ensemble. En cas de participation directe du film en céramique à la constitution de la structure portante, ce sont les caractéristiques mécaniques du film qui conditionneront largement les performances mécaniques de l'ensemble. Dans tous les cas le matériau mince et fragile est stabilisé par la structure portante.When mounting the thin ceramic plate on the supporting structure, it is mainly the supporting structure that will determine the characteristics of the assembly. In the event of direct participation of the ceramic film in the constitution of the bearing structure, it is the mechanical characteristics of the film which will largely determine the mechanical performance of the assembly. In all cases, the thin and fragile material is stabilized by the supporting structure.
Comme applications de ces panneaux en céramique mince et fragile on peut citer les panneaux décoratifs à apposer dont le poids est réduit vis-à-vis des matériaux massifs couramment utilisés, dont par suite le montage est facilité et dont la non propagation de la rupture à l'impact évite le risque de chute de parties d'éléments suspendus.As applications for these thin and fragile ceramic panels, mention may be made of decorative panels to be affixed, the weight of which is reduced vis-à-vis the massive materials commonly used, the assembly of which is consequently facilitated and the non-propagation of which breaks. the impact avoids the risk of falling parts of suspended elements.
On peut encore citer la fabrication d'éléments en céramique pour murs intérieurs, murs rideaux, revêtements de sol, parés d'une matière décorative mince et légère mais spécifiquement renforcée.We can also cite the manufacture of ceramic elements for interior walls, curtain walls, floor coverings, adorned with a thin and light decorative material but specifically reinforced.
Au niveau des applications pour la construction en général on peut citer la fabrication de portes ou d'éléments pour la fabrication de meubles.In terms of applications for construction in general we can cite the manufacture of doors or elements for the manufacture of furniture.
Au niveau de la construction ferroviaire ou aéronautique l'invention s'applique à la fabrication d'éléments décoratifs légers avec la face décorative très résistante à l'abrasion et aux égratignures.At the level of railway or aeronautical construction, the invention applies to the manufacture of light decorative elements with the decorative face very resistant to abrasion and scratches.
Grâce aux qualités conférées aux plaques minces stabilisées on trouve des possibilités d'emploi de celles-ci pour la fabrication de plaques réceptrices de chaleur ou de plaques chauffantes elles peuvent servir aussi de protection thermique.Thanks to the qualities conferred on the stabilized thin plates, there are possibilities of using them for the manufacture of heat-receiving plates or of heating plates, they can also serve as thermal protection.
Au niveau des applications on peut citer encore l'utilisation de ces plaques minces stabilisées comme support diélectrique pour la construction de circuits électriques ou électroniques.In terms of applications, mention may also be made of the use of these stabilized thin plates as a dielectric support for the construction of electrical or electronic circuits.
