Nanostructured composite materials for aerospace applications

In aerospace applications, the use of nanostructured materials is finalized to a significant improvement of the mechanical properties, Yoimg s modulus, ultimate strength, Poisson coefficient, etc. and reliability. In other sectors (e.g. electronics) the principal requirements are concentrated on the morphology characteristics of employed nanomaterials. In fact, the required quantities are always limited, and concurrent with their availabihty. Instead, for composites and structures, considering the large size of aerospace systems, the quantity and the relative costs represent a critical step. 

Analysis of results using mathematical/theoretical and numerical models, electronic microscopy, fracture mechanics and non-destructive testing. 

Comparing theoretical and experimental results allows us to understand the realistic behavior of these innovative materials. In particular, considering the cost of these materials, traditional composite materials are more competitive in terms of economic value and properties. This is a critical aspect with reference to the large dimensions of aerospace components and structures. 

During sample manufacturing processes, particular attention is required in the following steps  

Matrix de-gassing period, this is needed to reduce the micro-void embedded in the composite. This represents an important condition not only in the composite sector, but in nanotechnology application areas.
