Project: Nano Composite Material and Synthesis Technology for Enhanced Dynamic Stiffness

NanoComfort aims at enabling an advanced additive technological process for production of a new very versatile material for significantly reducing or eliminating parasitic vibrations of machines, machine components, and other machinery parts. The product is a structural-functional material family, a vibration absorbing nanocomposite that can be deposited on mechanical components, such as spindles, chucks, turbine blades, or on the clamping part of cutting tools, grinding tools, molds and dies. This completely passive damping solution, called EDS (Enhanced Dynamic Stiffness) material, requires minimal redesign for the components to be applied to. For the users this means enhanced machine precision, efficiency, quality, reliability, lifetime, and improved environmental conditions. The unique properties of EDS material family, besides the high vibration damping capacity, also include an ability to readily be deposited on complex curved surfaces, withstanding high mechanical loads without plastic deformations, and enduring high temperatures. Most importantly, the deposition rates attainable with this particular technology we believe will make the material economically viable for industrial scale manufacturing. Also from dynamic point of view, the material damping properties cover a wide frequency band that satisfies most operating needs of machines and machineries._x000D__x000D_The objectives of the NanoComfort project are: _x000D__x000D_1. investigation of the EDS material family at nano-, micro-, and macro-level, _x000D_2. validation and implementation of a new cutting-edge additive technological process for material synthesis,_x000D_3. development of HIGH POWER PULSED MAGNETRON SPUTTERING sources (High Current Low Duty Cycle Electric Discharges Source) to accelerate the deposition rates_x000D_4. automation and control of the process,_x000D_5. transfer from lab-scale prototype manufacturing to industrial scale production of EDS material. _x000D__x000D_Breakthroughs will be created in the developing of_x000D__x000D_- a unique class of damping stiff material with outstanding physical properties_x000D_- a radical new additive technology for material synthesis_x000D_- energy source for high material thickness at high deposition rates_x000D_- higher volume and cost effective production_x000D_- environmental friendly production_x000D__x000D_The European automotive, aerospace, naval, and manufacturing industries will have significant benefits from implementing damping composites for emerging applications in both low (cryogenic) and high temperatures as well as being effective over a wide frequency band. In each of these applications the advantages of composites are reduced weights through increased strength, reduced cost through elimination of expensive tooling and inspection procedures, and reduced complexity through elimination of previously used parts with fixed stiffness properties. _x000D__x000D_The global market for EDS material addressed in this proposal can have, if carefully considered, a huge economic impact.
