Zusammenfassung:	The invention relates to the field of manufacturing polymer nano-composites on a thermosetting binder for cosmic, aviation and building structures and for other structures (fibreglass-reinforced plastics, carbon-fibre-reinforced plastics, organoplastics, etc.). The problem addressed by the invention is that of increasing the strength of a nano-composite by optimizing the time taken by carbon nano-tubes to disperse in the binder, with the aim of achieving a maximum degree of dispersion of the carbon nano-tubes. In the method for producing a nano-suspension for manufacturing a polymer nano-composite, said method comprising introducing carbon nano-tubes into the composition of a thermosetting binder under ultrasonic action, the dispersion is carried out, with regard to the correspondence of the degree of dispersion of the carbon nano-tubes to the intensity of the colouring of the nano-suspension, with simultaneous photo-recording of the nano-suspension, and a standard degree of dispersion of the nano-particles is calculated according to a change in the intensity of the colouring, and the ultrasonic action is stopped when a value within the range of 0.9...0.99 is reached by the colouring. L'invention se rapporte à la production de nanocomposites polymères dans un liant réactif plastique pour des structures spatiales, aéronautiques, de construction et autres (plastiques à renfort de verre, plastiques à renfort de carbone, plastiques à renfort organique, etc.). Le but de la présente invention est d'augmenter la résistance du nanocomposite en optimisant le temps de dispersion de nanotubes de carbone dans le liant afin d'atteindre un taux de dispersion maximal des nanotubes de carbone. Le procédé de préparation d'une nanosuspension afin de préparer un nanocomposite polymère consiste à introduire des nanotubes de carbone dans la composition d'un liant réactif plastique en appliquant une action ultrasonique et, en tenant compte de la correspondance entre e taux de dispersion des nanotubes de carbone et de l'intensité de la coloration de la nanosuspension, on effectue la dispersion tout en effectuant un enregistrement photo de la nanosuspension; en fonction du changement d'intensité de coloration, on calcule le taux normatif de la dispersion de nanoparticules et on interrompt l'action ultrasonique lorsque sa valeur se situe dans une plage de 0,9,,,0,99.
