Title (EN) METHOD AND SYSTEM OF FEEDING A CARBON NANO TUBES (CNTS) TO A FLUID FOR FORMING A COMPOSITE MATERIAL
(FR) PROCÉDÉ ET SYSTÈME POUR ALIMENTER EN NANOTUBES (CNT) UN FLUIDE POUR FORMER UN MATÉRIAU COMPOSITE
Abstract: front page image
(EN)Disclosed herein is a method of feeding carbon nano tubes, CNTs, to a fluid wherein the CNTs are provided in the form of a powder of tangled agglomerates of CNTs, the powder of tangled agglomerates is fed to a dosing chamber (16, 18), a pressure pulse is applied to the dosing chamber (16, 18) to expel the CNTs from an outlet of the dosing chamber in such a way that the agglomerates are at least partially disintegrated by said pressure and accompanying shearing forces, and the CNTs are fed into said fluid to distribute said CNTs in said fluid and form a composite material.
(FR)La présente invention concerne un procédé permettant d'alimenter en nanotubes de carbone (CNT) un fluide. Ces nanotubes de carbone, qui se présentent sous forme d'une poudre d'agglomérats enchevêtrés de nanotubes de carbone, sont introduits dans une chambre doseuse (16, 18). En appliquant à la chambre doseuse (16, 18) une impulsion de pression, on expulse les nanotubes de carbone par un orifice de la chambre doseuse si bien que les agglomérats sont au moins partiellement désintégrés par la pression et les forces de cisaillement accompagnant cette pression. Enfin, les nanotubes de carbone sont introduits dans le fluide de façon à les répartir dans le fluide et à former un matériau composite.
