Summary:

Future aerospace developmental systems seek to further enhance both the mechanical and multifunctional properties of materials by incorporating nanoparticles. Advanced nanomaterials have extraordinary structural characteristics such as larger aspect ratios that promise the advent of a step improvement in technology and performance capability. Theoretical predictions and recent property measurements on individual carbon nanotubes suggest that they could form the basis of materials with exceptional mechanical and transport properties that have the potential to revolutionalize designs for future aerospace vehicles. However, there are a number of technical challenges that must be overcome before nanofilled materials can become commercially viable. A particular challenge is to integrate the favorable nanoparticle-enabled properties within hierarchical structured components using commercially viable processing methods while still achieving their predicted performance, e.g., weight savings, fatigue resistance, multifunctional properties, etc. A discussion on the challenges in pioneering nanostructures into future aerospace applications will be presented.
