Abrégé
(EN)
The present invention provides methods and systems for net shaped manufacturing using carbon nanotubes. Generally, an automatic control unit is used to place reaction units in the proper location to produce a component part of carbon nanotubes in a predetermined configuration. The reaction units include a carbon vaporization unit, a carbon feed/injection unit and a gas pressure/temperature control isolation unit. The carbon feed/injection unit advantageously operates to inject carbon based materials (e.g., graphite powder, solid graphite or carbon based gas) into a reaction area at a predetermined rate in which the carbon vaporization unit provides energy capable of dissociating carbon atoms from the injected carbon based material to produce a predetermined concentration of carbon vapor within the reaction area. The gas pressure/temperature control isolation unit operates to control the pressure and temperature of the reaction area to promote the growth of carbon nanotubes.

La présente invention concerne des procédés et des systèmes de fabrication à finition immédiate au moyen de nanotubes de carbone. On utilise en général une unité de commande automatique pour assurer le positionnement correct des unités de réaction et produire un composant de nanotubes de carbone selon une configuration déterminée. Les unités de réaction comprennent une unité de vaporisation de carbone, une unité d'alimentation/injection de carbone et une unité d'isolation à régulation de pression/température des gaz. L'unité d'alimentation/injection de carbone offre l'avantage de pouvoir injecter des matériaux à base de carbone (tels que poudre de graphite, graphite solide ou gaz à base de carbone) à un débit prédéterminé dans une zone de réaction dans laquelle l'unité de vaporisation de carbone fournit une énergie capable de dissocier les atomes de carbone due matériau injecté à base de carbone pour produire une concentration déterminée de vapeur de carbone au sein de la zone de réaction. L'unité d'isolation à régulation de pression/température du gaz règle la pression et la température de la zone de réaction pour favoriser la croissance de nanotubes de carbone.
