Description

CADRE DE RAQUETTE, ET RAQUETTE COMPRENANT UN TEL CADRE RACKET FRAME, AND RACKET COMPRISING SUCH A FRAME

L'invention concerne un cadre de raquette, ainsi qu'une raquette pourvue d'un tel cadre. L'invention vise plus particulièrement une raquette munie d'un tamis, telle que notamment une raquette de tennis, de badminton ou de squash.The invention relates to a racket frame, as well as a racket provided with such a frame. The invention relates more particularly to a racket provided with a sieve, such as in particular a tennis, badminton or squash racket.

On connaît, par exemple par US-A-6, 012 , 996, une telle raquette qui comprend un cadre réalisé en une matière plastique renforcée de fibres.We know, for example from US-A-6, 012, 996, such a racket which comprises a frame made of a plastic material reinforced with fibers.

Ce cadre fait appel à une multiplicité de feuilles superposées, dont chacune est formée de fibres imprégnées d'une résine en matière plastique.This framework uses a multiplicity of superimposed sheets, each of which is formed of fibers impregnated with a plastic resin.

L'invention se propose de réaliser un cadre de raquette constituant une alternative à l'art antérieur présenté ci- dessus .The invention proposes to provide a racket frame constituting an alternative to the prior art presented above.

A cet effet, elle a pour objet un cadre de raquette de tennis, comprenant un manche et un tamis, ce cadre étant réalisé, au moins en partie, en un matériau composite comprenant une résine en matériau plastique, ainsi que des fibres de renfort, caractérisé en ce que lesdites fibres de renfort comprennent des nanotubes de carbone .To this end, it relates to a tennis racket frame, comprising a handle and a sieve, this frame being made, at least in part, of a composite material comprising a plastic resin, as well as reinforcing fibers, characterized in that said reinforcing fibers comprise carbon nanotubes.

On entend, par nanotubes de carbone, des fibres creuses en carbone, possédant un diamètre de l'ordre du nanomètre, et dont la longueur est très nettement supérieure au diamètre précité.The term “carbon nanotubes” is understood to mean hollow carbon fibers, having a diameter of the order of a nanometer, and whose length is very much greater than the aforementioned diameter.

Ces nanotubes de carbone sont , par exemple décrits dans un article paru dans la revue "American Scientist" en juillet 1997, ou bien encore dans la revue "Le Temps stratégique" numéro 21, Genève, mai-juin 1998, ou bien encore dans "The Journal of British Interplanetary Society", volume 51, pages 145 à 152, 1998.These carbon nanotubes are, for example, described in an article published in the journal "American Scientist" in July 1997, or even in the review "Le Temps strategique" number 21, Geneva, May-June 1998, or even in " The Journal of British Interplanetary Society ", volume 51, pages 145 to 152, 1998.

Selon une autre caractéristique de l'invention, les fibres de renfort comprennent d'autres types de fibres, notamment de graphite et/ou de verre.According to another characteristic of the invention, the reinforcing fibers comprise other types of fibers, in particular graphite and / or glass.

L'invention a également pour objet une raquette, notamment de tennis, de squash ou de badminton, comprenant un cadre comportant un tamis, ainsi qu'un cordage tendu autour de ce tamis, caractérisée en ce que le cadre est tel que défini ci-dessus.The invention also relates to a racket, in particular tennis, squash or badminton, comprising a frame comprising a sieve, as well as a taut string. around this sieve, characterized in that the frame is as defined above.

Selon une caractéristique avantageuse de l'invention, cette raquette possède une masse inférieure à 280 grammes, une fois cordée.According to an advantageous characteristic of the invention, this racket has a mass of less than 280 grams, once strung.

Un procédé de fabrication du cadre de raquette, conforme à l'invention, va maintenant être décrit dans ce qui suit .A method of manufacturing the racket frame, according to the invention, will now be described in the following.

Il s'agit tout d'abord de former des feuilles, par imprégnation des nanotubes de carbone au moyen d'une résine en matière plastique, par exemple en epoxy. Cette opération d'imprégnation est réalisée, de façon connue en soi.It is first of all a question of forming sheets, by impregnation of carbon nanotubes by means of a plastic resin, for example in epoxy. This impregnation operation is carried out in a manner known per se.

Puis, ces feuilles sont superposées, de façon à former au moins un tube, et elles sont mises en forme par compres- sion et soufflage, selon des techniques également connues.Then, these sheets are superimposed, so as to form at least one tube, and they are shaped by compression and blowing, according to techniques also known.

Enfin, ces feuilles sont soumises à une opération de refroidissement, ce qui provoque leur durcissement.Finally, these sheets are subjected to a cooling operation, which causes them to harden.

Il est envisageable de former chaque feuille par imprégnation de nanotubes de carbone, associés avec d'autres fibres de renfort, telles que des fibres de verre ou des fibres de graphite.It is possible to form each sheet by impregnating carbon nanotubes, associated with other reinforcing fibers, such as glass fibers or graphite fibers.

Il est également possible de réaliser différents types de feuilles, dont certaines font appel uniquement à des nanotubes de carbone, alors que d'autres font appel uniquement à des fibres de renfort d'un type différent.It is also possible to produce different types of sheets, some of which use only carbon nanotubes, while others use only reinforcing fibers of a different type.

L'utilisation de nanotubes de carbone, en tant que fibres de renfort d'un cadre de raquette, est avantageuse.The use of carbon nanotubes, as reinforcing fibers of a racket frame, is advantageous.

En effet, une telle mesure permet d'augmenter de façon substantielle la rigidité du cadre, dans lequel sont présentes de telles fibres. Indeed, such a measure makes it possible to substantially increase the rigidity of the frame, in which such fibers are present.
