Extended Abstract: The invention «The method of dispersion of nanoparticles in epoxy resin (RU 2500706)» refers to nanotechnological field and it can be applied in different areas of machine industry, transport, construction, power engineering to increase strength and life span of the structures made of metal, composite and polymer, metallopolymer materials, for glue and glue and mechanical joints in different structure elements as well as for compositions which strengthen the stress concentration zones (in the form of holes, cutouts, fillet, thickness differentials) in structures, to reform defects, microcracks and other damages occurring in production and performance of structures, to eliminate and encapsulate the gaps in holes and meeting-points of bolted and riveted joints.
The invention «The method to produce nanosuspension for manufacturing polymer nanocomposite (RU 2500695)» refers to the area of production of polymer nanocomposites based on reactiveplastic binder for space, aircraft, construction and other types of structures (glass-fiber plastic, carbon reinforced plastic, organic plastic, etc.). The method includes preparation of nanosuspension by introducing carbon nanotubes into reactiveplastic binder under ultrasonic treatment with intensity cavity zone 15–25 kW/m². The method makes it possible to optimize the degree of dispersion of carbon nanotubes in binder and to shorten production time of nanocomposites possessing increased strength due to even distribution of nanoparticles in nanocomposite.
Key words: nanotechnologies, nanoparticles, nanosuspension, nanoepoxide dispersion, nanotubes, nanocomposites, nanomodified glue joint.
