In this paper, a new method for fabricating Ni80Fe20/Cu composite wires is presented. A series of samples were prepared by alternating the rotating direction of the Cu wire during RF magnetron sputtering. In order to keep the overall coating thickness of all the samples constant, the alternating...

This work presents the theoretical aspects of a one dimensional computational approach for the determination of the cross sectional stiffness of composite rotor blades. The method is based on a vector variant of the classical lamination theory embedded into a geometrically exact large...

В статье рассмотрена возможность получения композиционных материалов на основе металлического никеля и сверхтвердых материалов. Установлено, что такой...

The article considers a possibility of making composite materials from metal nickel and super-hard materials. It shows that such a product is available in the world market, but there is no information on technology of manufacture of such a product in open literature. It sets the issue of...

TiC and TiB2 reinforced iron based metal matrix composite (MMC) coating was synthesized on mild carbon steel by laser cladding employing B4C, ferrotitanium, and FeCrSiB mixed powders. The microstructure and chemical composition were analyzed by means of SEM, EPMA, and XRD. Results show that the...

Sulfonated ultra-thin proton-exchange polymer membrane carrying pyridine groups was made from a plasma polymerization of styrene, 2-vinylpyridine, and trifluoromethanesulfonic acid by after-glow capacitively coupled discharge technique. Pyridine groups tethered to the polymer backbone acts as a...

A review of structural health monitoring methods, including residual cure strain monitoring is presented for the wind turbine blade industry. A comparison is presented for dielectric, acoustic, ultrasonic, thermal and fibre optic monitoring methods. This review highlights the need for further...

The paper describes the latest trends and forecasts of R&D in the aerospace industry. Particular attention is paid to dual-use technologies that used both military and civil sector, and nanotechnology developments. A number of concepts of future aircraft are discussed that are currently being at...

We derive the first dynamic correction to the effective refractive index for a square array of cylinders (of finite or infinite refractive index), subject to a low-frequency incident radiation. This correction also imposes constraints on the wave number region for which the Lorentz-Lorenz...
