15 2 Cleansky projects in Projects have been funded in 2010: Organocs (100Keuro) and Thermocs (60Keuro) Projects of Green Regional Aircraft topic: development of advanced resin systems for composites The objectives were the manufacturing of nanomodified epoxy resin systems with various nanoparticles, various contents (from 0.1% to 15%) and various surface modifications. Nanoparticles has been selected among: 1D needle shape: Carbon Nanotubes (Baytube GmbH) 1D needle shape: Carbon Nanofibres (Showa Denko K.K.) 2D plate shape: Nanoclay (Southern Clay Products Inc. ) 3D ball shape: Zircon Dioxide (Evonik Degussa GmbH), Boehmite (AlOOH, Sasol GmbH) Dispersion techniques developed at AAC have been used. The results demonstrated the specific influence of each nano-reinforcements, e.g.: Increase of the electrical conductivity with carbon nanofibres Increase of the impact resistance with carbon nanotubes Increase of the resin stiffness with ceramic nanoparticles The project also demonstrated the difficulties to combine them to obtain a high performance resin

16 Nanoparticles: nanometers Carbon nanotubes: impact resistance Carbon nanofibers: electrical conductivity Alumina nanoparticles: stiffness Difficulties: Fine structure! Dispersion! Stabilisation! De-agglomeration! Open for further developments: The most efficient combination!

17 1 Cleansky project to be started in Project is currently under negotiation: FOS3D (ca. 590 k ) within the Smart Fixed Wing Aircraft topic: JTI-CS SFWA The objective of FOS3D is the development and Testing of a Fiber Optic System for Deflection and Damage Detection in order to control actively actuated morphing wing structures Consortium: AAC project leader IMA project partner FOS3D concept Fiber optic coil sensor Fiber optic cable Opto-electronic device Preamplifiers with bandpass ( khz) Low-pass (< 100 Hz) AE channels analog input channels Acoustic Emission System
