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.

Abstract: A method for composite material synthesis at the surface of a work piece, wherein it includes PECVD, PEPVD methods and plasma generation by electric discharges with closed electron drift. The composite material comprises at least one layer of substantially parallel carbon pillars extending from the bottom surface of the at least one layer up to the top surface of the at least one layer. The carbon pillars have a cross-sectional dimension in the range of 50-200 ?m, and heights in the range of 50 ?m-2 mm.

Abstract: A composite, carbon based material that can be used for enhancing the dynamic stiffness of objects, in the case where it for instance is applied as a coating, comprises at least one layer of substantially parallel carbon pillars. The pillars extend from the bottom surface up to the top surface of the layer, substantially perpendicularly to said surfaces, have substantially hexagonal or pentagonal cross-sections and a relatively weak conical shape, their cross-section widening from their bottom ends to their top ends. The carbon based pillars can typically have a cross-sectional dimension in the range of 50-200 ?m such as about 100 ?m and have heights in the range of 50 ?m-2 mm. The pillars can be seen as built from macro-sized aggregates that have at least one dimension in the nano range, e.g. in the range of 10-800 run, and include carbon, oxygen and hydrogen and in most cases also nitrogen.
