Aerospace 4

  1. 1. Application of Nanocomposites in Aerospace<br />
  2. 2. NANOMATERIAL AND NANOTECHNOLOGIES<br />The interest in nano-materials and nano-technologies is a direct consequence of the synthesis of fullerenes in 1985 (Smalley and Kroto), the third existence form of carbon, a stable and ordered structure, besides the already existing diamond and graphite. <br />
  3. 3. Aerospace Applications<br />
  4. 4. APPLICATIONS OF NANOMATERIALS<br />In aircraft construction the nanocomposites represent an advanced material solution:<br />In aircraft construction as strengthening element for the structure (stringers, frames) or as skin for the honeycomb type structures use at wings and fuselage.<br />Base materials for high temperatures, the nano carbon-carbon composites were first developed for the aerospace technology (components and missiles, re-entry vehicles, space shuttles and as a brake lining and brake disk material for civil and military aircraft. These materials with nanoadditivated ceramic matrix represents the potential unique solution for the radoms of the hypersonic airplanes<br />Nanocomposites with the form of zirconia based complex nanopowders are used as thermal protection for pieces of turboengines<br />
  5. 5. NANOMATERIALS<br />Carbon-carbon composites consisting of a carbon fiber reinforced structure embedded in a polymer matrix or mesophases that through a proper heat treatment transforms all in carbon<br />Oil mesophase additives with CNT<br />Tubular structure of MWCNT<br />Carbon Nanofibers<br />
  6. 6. NANOMATERIALS<br />Nanocomposites with epoxy or polyamide matrix additivated with two types of nanofillers: laser-synthesized nanocarbon and layered silicate<br />Structural carbon fiber reinforced composites with a matrix made from the two types of nanocomposites.<br />Nanocomposite Epoxy/ MMT<br />Nanocomposite Epoxy/ CNT<br />
  7. 7. NANOCOATINGS<br />Multilayer structure, ceramics, temperatures resistant, thermal shock, corrosive and erosive wear, fritting, etc. applied at turbo engines and modern co-generative systems.<br />ZrO2 based thermal barrier coatings.<br />Monolayer protections, vitro ceramics, related to functional conditions of turbo engines for “hot parts” protections.<br />Mono and multilayers protection, for complex alloys, temperature resistant, corrosive and erosive wear, liquid metal contact resistant. <br />
  8. 8. NANOCOATINGS<br />The properties of thermal barrier coatings (TBC) achieved using nano-particles:<br />The adherence is rising with 10%<br />Decrease the oxygen permeability<br />Increase the resistance at quick thermal shock with 100°C/ sec<br />
  9. 9. JET ENGINE APPLICATIONS<br />
  10. 10. BENEFITS<br />Fracture Toughness<br />Microcracking<br />High Temperature Frames, Cases, Ducts<br />Thermal Conductivity<br />Anti-Icing<br />Front frames<br />Electrical Conductivity<br />Grounding: By-pass ducts<br />Lightning Strike: Nacelles<br />Coefficient of Thermal Expansion<br />Microcracking, Residual Stresses<br />Ply Build-ups, Molding Compound<br />High Temperature Frames, Cases, Ducts<br />Service Temperature<br />Flange Compressive Strength<br />High Temperature Frames, Cases, Ducts<br />Permeability<br />Composite Hydraulic Tubing<br />
  11. 11. BOEING 7E7<br />
