NANO-FILLER TECHNOLOGIES CHARACTERIZATION FOR SMART AERONAUTICAL APPLICATIONS

The use of composite materials is becoming increasingly widespread in many aeronautical applications. The improved endurance and corrosion resistance are few of the advantages they can offer, compared to the conventional isotropic solutions. In this context, the research team led the design and manufacturing of carbon fiber-reinforced composite panels, including different filler infusions based on carbon nanotubes (CNTs) technology. The vibroacoustic tests have been carried out on several samples for the characterization of the damping as well as the transmission loss properties related to such micro-handling treatments. The results obtained in such framework allowed for highlighting that, in order to achieve the best overall vibro-acoustic behaviour, an optimum compromise can be achieved, targeted to suitably combine the various chemical and structural characteristics of the analysed specimens.
