Nanocomposites based on AlSi9Cu3(Fe) alloy and cabon nanotubes, preparation and properties

Throughout last few decades, the main research area regarding reducing CO2 footprint is developing new materials, which can be used as lighter parts for transport industry. Majority of work is conducted concerning the potential usage of new nanocomposites based on metal or polymer matrix with improved mechanical properties. This improvement could result in production of smaller and thicker vehicle parts with overall less weight. In this work, new nanocomposites based on AlSi9Cu3(Fe) alloy and carbon nanotubes were prepared using high pressure die casting machine. Nanotubes, varying in mass ratio, were placed on two different positions inside the machine. Structure and stability of nanotubes in nanocomposite were confirmed using scanning electron microscopy (SEM). Mechanical properties and metallographic investigation of prepared nanocomposites and base alloy were studied using tensile testing machine and optical microscope. According to experiment conditions nanocomposites showed different mechanical properties when compared to base alloy.
