Nanocomposites have various applications in aircraft construction and jet engines due to their beneficial properties. They can be used as strengthening elements in aircraft structures or as skin for honeycomb structures on wings and fuselages. Carbon-carbon composites with carbon fiber reinforcement and polymer or carbon matrices are used for high temperature components. Nanocomposites with zirconia matrices provide thermal protection for turboengine parts. Nanocoatings made from ceramics with nano-particles can increase adhesion, decrease oxygen permeability, and improve resistance to thermal shock for thermal barrier coatings on jet engines.

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.

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
