Aluminum is a very useful structural metal employed in different industrial sectors, in particular it is used in\udlarge quantities in automotive, aeronautic and nautical industries. The main reasons of its wide use are: a very\udgood oxidation resistance, excellent ductility, low melting temperature (660 °C) and low density (2.71 g/cm3).\udHowever, in order to reduce the emissions and fuel consumption is necessary to reduce the overall weight of\udvehicles by increasing mechanical properties of the structural material. The improvement of mechanical\udproperties is normally achieved through use of reinforcement in materials, used like matrix, in order to improve\udsome specific characteristics.\udIn this work composites of carbon nanotubes (CNTs) dispersed in aluminum were made. The most difficulties\udin the preparation of this type of composite are represented by the low wettability between metallic matrix and\udfillers and the possibility of the oxidation of metal during melting with consequent decreasing of mechanical\udproprieties. The composite was obtained by three consecutive step: the first one is the functionalization of\udfillers surface to improve the fillers dispersion, the second one is the dispersion of fillers in the matrix by\udpowder mixing and the third one is the melting and casting of the mix prepared.\udIn particular, fillers used are multi walled carbon nanotubes (MWCNTs) with functionalized surface by\udtreatment with a solfonitric solution. Melting and casting are carried out with the aid of an induction furnace\udwith a controlled atmosphere system and centrifugal casting. Argon is the inert gas used to prevent the\udoxidation of aluminium during fusion. Young’s modulus was evaluated at different temperature and correlated\udwith the different CNTs percentage. The dispersion rate of fillers and the microstructure of the sample were\udevaluated by FESEM micrograph
