Description
La présente invention est relative à un produit composite. Elle concerne en premier lieu un produit constitué dudit composite permettant de réaliser une barrière aux radiations visibles, ou invisibles telles qu'infrarouges, par réflexion desdites radiations seules ou combinées entre-elles.

It also makes it possible to produce a fire barrier while exhibiting good mechanical characteristics such as the flexural strength and the tensile strength.
Il est connu de réaliser des produits composites comprenant une feuille d'aluminium assemblée à un autre matériau tel que de la laine de verre. Les produits réalisés selon cette technique peuvent présenter des faiblesses mécaniques et des difficultés de réalisation dues à la discontinuité du matériau qui demande des étapes supplémentaires dans le procédé de fabrication. It is known to produce composite products comprising an aluminum sheet assembled with another material such as glass wool. The products produced according to this technique can have mechanical weaknesses and production difficulties due to the discontinuity of the material which requires additional steps in the manufacturing process.
Le produit selon l'invention permet de remédier à cet inconvénient. The product according to the invention overcomes this drawback.
Il est en effet constitué de la combinaison d'au moins un matériau à liant hydraulique avec des fibres élaborées en alliages métalliques amorphes à base de fer, de phosphore, de carbone et de chrome, du type suivant lequel on refroidit très rapidement un alliage métallique en phase liquide de manière à obtenir une structure vitreuse, la phase liquide étant préparée à partir de fonte, de phosphore et de chrome, en particulier les fibres sont en alliage amorphe ayant la composition suivante en pourcentage atomique : Cr : 1,5 à 8 ; C : 8 à 16
P : 4 à 12 ; Si : jusqu'à 3,5 ; le reste étant du fer et le rapport P/C étant inférieur à 1.It is in fact made up of the combination of at least one material with a hydraulic binder and fibers produced from amorphous metal alloys based on iron, phosphorus, carbon and chromium, of the type according to which a metal alloy is cooled very quickly. in the liquid phase so as to obtain a glassy structure, the liquid phase being prepared from cast iron, phosphorus and chromium, in particular the fibers are made of amorphous alloy having the following composition in atomic percentage: Cr: 1.5 to 8 ; C: 8 to 16
P: 4 to 12; If: up to 3.5; the rest being iron and the P / C ratio being less than 1.
Suivant d'autres caractéristiques,

diamètre des grains est inférieur à 2 mm
- le matériau à liant hydraulique est à base de
sulfate de calcium, tel que du plâtre.According to other characteristics,
- the percentage of reinforcement in metallic fibers in
ribbon shape ranges from 0.1 to 6% by total weight
- the hydraulic binder material is a
cement micro mortar; a cement micro mortar
is a mortar comprising sand, the
grain diameter is less than 2 mm
- the hydraulic binder material is based on

L'invention a également pour objet un procédé de fabrication d'un produit comportant des étapes dans lesquelles on mélange un matériau à liant hydraulique et des fibres métalliques en forme de ruban discontinu, élaborées en alliages métalliques amorphes à base de fer, phosphore, de carbone et de chrome, du type suivant lequel on refroidit très rapidement un alliage métallique en phase liquide de manière à obtenir une structure vitreuse, la phase liquide étant préparée à partir de fonte, de phosphore et de chrome, puis on projette ou on coule et vibre le mélange, ensuite on mûri le produit en ambiance humide. The subject of the invention is also a method of manufacturing a product comprising steps in which a material with a hydraulic binder and metallic fibers in the form of a discontinuous ribbon are mixed, made of amorphous metal alloys based on iron, phosphorus, carbon and chromium, of the type according to which a metallic alloy is very rapidly cooled in the liquid phase so as to obtain a vitreous structure, the liquid phase being prepared from cast iron, phosphorus and chromium, then it is sprayed or poured and vibrates the mixture, then the product is matured in a humid atmosphere.
L'invention a encore pour objet l'utilisation du produit comme constituant d'un revêtement ou d'un panneau apte à établir une barrière aux radiations visibles et/ou invisibles telles qu'infrarouges et l'utilisation du produit comme constituant d'un panneau ou un revêtement coupe-feu. Another subject of the invention is the use of the product as a constituent of a coating or a panel capable of establishing a barrier to visible and / or invisible radiation such as infrared radiation and the use of the product as a constituent of a fire-resistant panel or coating.
On fournira maintenant un exemple de mise en oeuvre de 1 invention appliqué au procédé de fabrication d'une cloison coupe-feu. We will now provide an example of implementation of the invention applied to the method of manufacturing a fire wall.
Dans cet exemple le produit composite est constitué de fibres en alliage amorphe ayant la composition suivante en pourcentage atomique : Cr : 1,5 à 8 ; C : 8 à 16
P : 4 à 12 ; Si : jusqu'à 3,5 ; le reste étant du fer et le rapport P/C étant inférieur à 1 et d'un matériau à liant hydraulique à base de sulfates de calcium. Les fibres sont sous la forme de ruban, c'est-à-dire allongées et plates.In this example, the composite product consists of fibers of amorphous alloy having the following composition in atomic percentage: Cr: 1.5 to 8; C: 8 to 16
P: 4 to 12; If: up to 3.5; the remainder being iron and the P / C ratio being less than 1 and of a material with a hydraulic binder based on calcium sulfates. The fibers are in the form of a ribbon, that is to say elongated and flat.
Dans une première étape on mélange le matériau à base de sulfates de calcium aux fibres dans une proportion de 0,1 à 6 % de fibres avec de l'eau dans une quantité qui permette l'obtention d'un mélange facilement coulable ou projetable. In a first step, the material based on calcium sulphates is mixed with the fibers in a proportion of 0.1 to 6% of fibers with water in an amount which makes it possible to obtain an easily pourable or sprayable mixture.
Puis dans une deuxième étape on coule le mélange dans un moule. Ce moule est un caisson formant une empreinte parallélépipédique. Then in a second step we pour the mixture into a mold. This mold is a box forming a parallelepiped footprint.
La Demanderesse a constaté que les fibres se placent parallèlement à la surface externe de la cloison, ce qui permet d'assurer la régularité de la réflexion de la chaleur sur tout le revêtement ainsi qu'une orientation préférentielle des fibres pour l'obtention d'une bonne résistance mécanique. Les fibres se chevauchent les unes par rapport aux autres ce qui a permis au liant hydraulique de se répartir au-dessus et en dessous des fibres. Ainsi les fibres constituent une armature métallique qui renforce les propriétés mécaniques du revêtement. Le produit selon l'invention permet, en conséquence, de combiner une réflexion uniforme et un renforcement mécanique. En variante la densité de fibres est augmentée dans la couche de surface de manière à former un revêtement, auquel cas la fibre peut être supprimée au niveau du centre de l'épaisseur du panneau. The Applicant has found that the fibers are placed parallel to the external surface of the partition, which makes it possible to ensure the regularity of the reflection of heat over the entire coating as well as a preferential orientation of the fibers for obtaining good mechanical resistance. The fibers overlap with respect to each other which allowed the hydraulic binder to spread above and below the fibers. Thus the fibers constitute a metallic reinforcement which reinforces the mechanical properties of the coating. The product according to the invention therefore makes it possible to combine uniform reflection and mechanical reinforcement. Alternatively the fiber density is increased in the surface layer so as to form a coating, in which case the fiber can be removed at the center of the thickness of the panel.
La cloison est réalisée à une épaisseur de 1 à 15 cm, le matériau à base de sulfate de calcium peut être un mélange plâtre + eau de rhéologie suffisante permettant une mise en place aisée. The partition is made at a thickness of 1 to 15 cm, the material based on calcium sulphate can be a plaster + water mixture of sufficient rheology allowing easy installation.
Dans une troisième étape, cet ensemble moule + matériau est mûri en enceinte à 200C pendant 24 heures ou en température par exemple 500C 100 %
HR (humidité relative) pendant 3 heures. In a third step, this mold + material assembly is matured in a chamber at 200C for 24 hours or at a temperature, for example 500C 100%
RH (relative humidity) for 3 hours.
