1. Application of Nanocomposites in Aerospace

2. NANOMATERIAL AND NANOTECHNOLOGIES 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.

3. Aerospace Applications

4. APPLICATIONS OF NANOMATERIALS In aircraft construction the nanocomposites represent an advanced material solution: In aircraft construction as strengthening element for the structure (stringers, frames) or as skin for the honeycomb type structures use at wings and fuselage. 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 Nanocomposites with the form of zirconia based complex nanopowders are used as thermal protection for pieces of turboengines

5. NANOMATERIALS 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 Oil mesophase additives with CNT Tubular structure of MWCNT Carbon Nanofibers

6. NANOMATERIALS Nanocomposites with epoxy or polyamide matrix additivated with two types of nanofillers: laser-synthesized nanocarbon and layered silicate Structural carbon fiber reinforced composites with a matrix made from the two types of nanocomposites. Nanocomposite Epoxy/ MMT Nanocomposite Epoxy/ CNT

7. NANOCOATINGS Multilayer structure, ceramics, temperatures resistant, thermal shock, corrosive and erosive wear, fritting, etc. applied at turbo engines and modern co-generative systems. ZrO2 based thermal barrier coatings. Monolayer protections, vitro ceramics, related to functional conditions of turbo engines for “hot parts” protections. Mono and multilayers protection, for complex alloys, temperature resistant, corrosive and erosive wear, liquid metal contact resistant.

8. NANOCOATINGS The properties of thermal barrier coatings (TBC) achieved using nano-particles: The adherence is rising with 10% Decrease the oxygen permeability Increase the resistance at quick thermal shock with 100°C/ sec
