Abstract: Composite reinforcement “Astrofleks” is used in building structures for reinforcement of insulation wall panels, solid concrete and prefabricated buildings. The composite reinforcement comprises the outer layer (1), inside of which the inner layer (2) is placed, on the outer surface of outer layer (1) there are relief elements (3) to improve adhesion of nanocomposite reinforcement with concrete. According to embodiment number 1, layer (1) is made of nanocomposite carbon in which the polymer matrix is modified by carbon nanostructures. Layer (2) is made of lightweight highly mobile concrete, containing in its composition components in the following ratio (% wt.): Cement—20-50; filler—70-30; plasticizer—0.02-2.5; water—the rest. According to embodiment number 2, layer (1) is made of nanocomposite carbon in which the polymer matrix is modified by polyhedral multi-layered carbon nanostructures of fulleroid type at a ratio of 0.01-10% by weight of the polymer matrix.

Abstract: A tool for machining parts and particularly surfaces of parts includes a machining head and a main, supporting body (3) made of carbon fibers bonded by a polymer binder and additionally contains polyhedral multilayer carbon nanostructures of the fulleroid type having e.g. a layer-to-layer distance of 0.34-0.36 nm, taken in a quantity of 0.05-50 wt % of the mass of the polymer binder. The main body thereby obtains an increased stiffness and strength.
Abstract: The invention relates to a nanocomposite material that contains a polymer binder, a filler and a fraction of nanoparticles, characterized in that the fraction of nanoparticles comprises multi-layered carbon particles having a toroid-like shape with a size of 15 to 150 nm, wherein the ratio between the outer diameter and the thickness of the toroid body is in a range of (10-3):1. This nano-modification makes it possible to obtain an efficient compaction and hardening of the nanocomposite material close to the filler/binder inter-phase barrier, and accordingly to increase the average density, elasticity, hardness and resistance of the material. The invention can be used for making various parts and articles for use in mechanical engineering and transport, including instrument holders for the precise surface treatment of parts.
