Cette invention a trait à des structures composites qui sont obtenues en enroulant  This invention relates to composite structures which are obtained by winding

un brin de matériau métallique autour ou avec un filament de céramique.  a strand of metallic material around or with a ceramic filament.

On connaît une méthode pour former des structures légères comprenant des filaments de céramique avec des fils de titane tordus autour d'eux. Ces structures sont ensuite enroulées les unes autour des autres à la façon d'une corde à plusieurs brins, à  A method is known for forming light structures comprising ceramic filaments with titanium wires twisted around them. These structures are then wrapped around each other like a multi-strand rope,

L'avantage obtenu par cette structure connue est que les filaments de céramique sont séparés les uns des autres. Cela est une condition critique dans tous les cas o les structures bobinées doivent être ensuite formées, par pressage à chaud ou de façon  The advantage obtained by this known structure is that the ceramic filaments are separated from each other. This is a critical condition in all cases where the coiled structures must then be formed, by hot pressing or

Conformément à la présente invention, le procédé de fabrication d'un article léger qui inclut les étapes d'enrouler des fils de métal léger et des filaments de céramique, puis de bobiner la structure résultante à rintérieur d'une préforme, comprend l'étape supplémentaire de remplir les interstices au sein de la préforme avec un métal de façon  In accordance with the present invention, the method of manufacturing a light article which includes the steps of winding light metal wires and ceramic filaments, then winding the resulting structure inside a preform, includes the step additional filling the interstices within the preform with a metal so

à donner une structure dense dans la forme finale.  to give a dense structure in the final form.

L'invention va à présent être décrite au moyen d'un exemple et en faisant référence au dessin joint qui est une vue de l'extrémité d'une structure semblable à une corde de filaments de céramique et de fils légers qui incorpore une forme de réalisation  The invention will now be described by way of an example and with reference to the accompanying drawing which is a view of the end of a structure similar to a cord of ceramic filaments and light wires which incorporates a form of production

de la présente invention.of the present invention.

En se référant au dessin. Des filaments 10 de céramique présentent, entourés autour d'eux, des fils de titane dont certains sont indiqués par le chiffre 12. Les structures de fils enroulés sont ensuite bobinées les unes autour des autres pour constituer, au moins dans le présent exemple, une structure 14 semblable à une corde à  Referring to the drawing. Ceramic filaments 10 have, surrounded around them, titanium wires, some of which are indicated by the number 12. The wound wire structures are then wound around each other to constitute, at least in the present example, a structure 14 similar to a rope

trois brins. Tout cela est toutefois connu.  three strands. All this is known, however.

Ce qui n'est pas connu est un matériau de matrice en métal 16 qui est infiltré au sein des interstices de la structure après qu'elle a acquis une forme à l'intérieur d'une  What is not known is a metal matrix material 16 which is infiltrated within the interstices of the structure after it has acquired a shape inside a

préforme, par exemple un anneau (non représenté).  preform, for example a ring (not shown).

Le métal infiltré doit être d'un type tel que son point de fusion est inférieur à celui des fils de titane. Par exemple, cela peut être du magnésium, de l'aluminium, un alliage  The infiltrated metal must be of a type such that its melting point is lower than that of the titanium wires. For example, it can be magnesium, aluminum, an alloy

convenable d'aluminium ou du nickel.  suitable aluminum or nickel.

L'infiltration par le métal peut être effectuée tandis que ce dernier est appliqué sous forme liquide ou sous forme vapeur. Cela implique la nécessité, lors de l'application, de fournir de la chaleur. Donc le procédé d'application à retenir est celui qui garantit le temps minimum pendant lequel la structure sera exposée à la chaleur de  The metal infiltration can be carried out while the latter is applied in liquid or vapor form. This implies the need, during application, to provide heat. So the application method to be used is that which guarantees the minimum time during which the structure will be exposed to the heat of
