The inclusion of nanotubes is made by functionalization or sonication techniques. A leader is connected to the device through bonding or welding process.

Description

La présente invention concerne un hameçon de pêche de nouvelle génération, The present invention provides a new generation of fishing hook

possédant la propriété de transparence ou de translucidité. having the property of transparency or translucency.

Un hameçon de pêche est un dispositif de piégeage et de capture de poisson constitué d'une hampe terminée à l'une de ses extrémités par un système d'attache au bas 5 de ligne, et à l'autre extrémité par une pointe acérée ou un ardillon. A fishing hook is a trapping device and fish catch consists of a shank terminated at one of its ends by attachment to the bottom line 5 system, and at the other end with a sharp point or barb.

Les hameçons traditionnels utilisés par les pêcheurs sont réalisés par forgeage d'aciers suivi d'un traitement de surface. Conventional hooks used by fishermen are made by forging steel followed by a surface treatment. Ainsi réalisés ils possèdent des propriétés mécaniques (module d'Young, résistance mécanique, dureté) qui les rendent aptes à l'emploi, quand bien même l'hameçon accrocherait un obstacle ou le poisson ferré serait de taille importante (donc exerçant sur l'hameçon une force conséquente) : dans chaque cas, la perte du bas de ligne est due à la rupture du fil de pêche plutôt qu'à celle de l'hameçon. So they have made of the mechanical properties (Young's modulus, strength, hardness) that make them suitable for use, even if the hook cling an obstacle or the hooked fish would be of significant size (thus exerting on the hook a substantial force): in each case, the loss of the leader is due to rupture of the fishing line rather than that of the hook.

Afin d'ajouter une propriété de transparence ou de translucidité à l'hameçon traditionnel, il est nécessaire d'employer pour sa réalisation un matériau amorphe (polymère ou verre minéral). To add a property of transparency or translucency to the traditional hook, it is necessary to use for its realization an amorphous material (polymer or mineral glass).

Compte tenu de la faible ténacité des verres minéraux ceux-ci ne sont pas proposés ici comme candidats à la substitution des hameçons métalliques. Given the low toughness glasses minerals they are not offered here as candidates for substitution metal hooks.

Les polymères quant à eux possèdent les qualités de ductilité nécessaires à leur mise en forme, donc à leur utilisation comme matériau de substitution. The polymers in turn have the ductility of qualities necessary for their layout, so their use as substitute material. En revanche, ils sont handicapés par la faible valeur de leur module d'Young, qui se révèle insuffisante pour assurer la traction de la proie capturée, ainsi que par leur dureté trop faible pour permettre l'obtention d'un ardillon suffisamment acéré. However, they are handicapped by the low value of their Young's modulus, which is insufficient to provide traction of the captured prey, as well as their low hardness to enable obtaining a sufficiently sharp barb.

Nous proposons donc d'améliorer la ténacité, le module de traction, la dureté ainsi que d'abaisser la contrainte maximale au sein d'un hameçon en polymère par deux méthodes complémentaires. We therefore propose to improve the toughness, the tensile modulus, hardness and lower the maximum stress in a polymer hook by two complementary methods. La première est destinée à augmenter le module d'Young, la dureté et la ténacité du matériau, et la seconde permet, à taille de proie donnée, de diminuer la contrainte maximale subie par le matériau lors de la traction exercée par le poisson. The first is intended to increase the Young's modulus, hardness and toughness of the material, and the second makes it possible, given prey size, decrease the maximum stress experienced by the material during the traction exerted by the fish.

La première méthode consiste à inclure à l'état de dispersion des structures nanotubulaires au sein de la matrice polymérique dont est constitué l'hameçon afin d'accroître son module de traction, sa ténacité et sa dureté. The first method is to include in the dispersion state of the nanotube structures within the polymer matrix making up the hook in order to increase its tensile modulus, toughness and hardness. Seront utilisés pour cela des nanotubes monoparois (SWNT: Single Wall Carbon Nanotube), aspect non limitatif. It will be used for the single-walled nanotubes (SWNT: Single Wall Carbon Nanotube), non-limiting aspect.

L'inclusion de ces nanotubes dans la matrice du matériau peut se faire par fonctionnalisation ou par sonication, techniques non limitatives. The inclusion of these nanotubes in the material matrix can be by functionalization or by sonication, non-limiting techniques.

Appliquer cette technique à un matériau polymère transparent tel que le PMMA (PolyMethyl MethAcrylate) matrice plastique non limitative, permet d'élaborer des hameçons de pêche transparents ou translucides aux propriétés susmentionnées performantes. Apply this technique to a transparent polymer material such as PMMA (polymethyl methacrylate) non-limiting plastic matrix makes it possible to develop transparent or translucent fishing hooks to performing the aforementioned properties.

La seconde méthode consiste à modifier le profil de la section transversale de l'hameçon, afin d'abaisser la contrainte maximale pouvant être appliquée au matériau avant rupture. The second method consists in modifying the profile of the cross section of the hook, in order to lower the maximum stress that can be applied to the material before rupture.

Il est proposé d'utiliser une section à profil continu et convexe de manière à augmenter le moment quadratique, sans que la lumière passant au travers du matériau ne subisse trop de changements d'interface, et donc réfracte un trop grand nombre de fois. It is proposed to use a continuous profile section and convex so as to increase the second moment without the light passing through the material does not suffer too much of interface changes, and thus refracts too many times.

Par exemple, des calculs démontrent qu'une section elliptique permet de diminuer la contrainte maximale d'un hameçon de section circulaire de 20%, ce profil de section étant non limitatif. For example, calculations show that an elliptic section reduces the maximum stress of a circular section of hook 20%, this section profile being non-limiting.

L'application conjuguée de ces deux méthodes pour un hameçon en matière plastique transparente permet ainsi d'obtenir un hameçon transparent ou translucide capable de concurrencer les propriétés mécaniques d'un hameçon métallique classique. The combined application of these methods to a transparent plastic hook thus makes it possible to obtain a transparent or translucent hook capable of competing with the mechanical properties of a conventional metal hook.

L'hameçon ainsi renforcé pourra être réalisé en les matériaux suivants: copolymère éthylène chlorotrifluorethylène (Halar ECTFE), éthylène tetrafluoroéthylène (Teftzel ETFE), éthylène propylène fluoré (Teflon FEP) , polyéthylène (HDPE, LDPE), polyéthylène fluoré (FLPE), polycarbonate (PC), copolyester de polyéthylène téréphtalate (PETG), perfluoroalkowy (Teflon PFA), polycétone, polyméthyl méthacrylate (PMMA), polyméthylpentène (PMP TPX), polypropylène (PP), copolymer de polypropylène (PPCO), polystyène (PS), polysulfone (PSF), polyuréthane (PUR), polyvinyle de chlorure (PVC), polyvinylidène de fluorure (PVDF), styrène acryonitrile (SAN), élastomère thermoplastique (TPE), nylon, résine. The hook thus reinforced can be made of the following materials: ethylene chlorotrifluoroethylene copolymer (Halar ECTFE), ethylene tetrafluoroethylene (ETFE Teftzel), fluorinated ethylene propylene (Teflon FEP), polyethylene (HDPE, LDPE), fluorinated polyethylene (EPLF), polycarbonate (PC), copolyester polyethylene terephthalate (PETG), perfluoroalkowy (Teflon PFA), polyketone, polymethyl methacrylate (PMMA), polymethylpentene (PMP TPX), polypropylene (PP), polypropylene copolymer (COPP), polystyène (PS), polysulfone (PSF), polyurethane (PUR), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), styrene acryonitrile (SAN), thermoplastic elastomer (TPE), nylon, resin.

Dans le but d'éviter la réalisation d'un noeud et de faciliter la jonction, et l'hameçon étant constitué d'un matériau plastique, il pourra être relié au bas de ligne par collage, technique non limitative. In order to avoid the production of a node and to facilitate the junction, and the hook being formed of a plastic material, it may be connected to the leader by bonding, non-limiting technique.

De plus, du fait de sa dureté accrue par la première solution, si l'hameçon en 35 plastique comportait un ardillon, celui-ci pourra être usiné pour le rendre acéré. In addition, due to its increased hardness by the first solution, if the hook 35 included a plastic pin, it can be machined to make it sharp.
