Examination of mechanical behaviour of fullerene doped aluminium matrix composite produced by sintering process

Abstract

The primary goal of this research is to understand the mechanical properties of Aluminium composite structures doped with different fullerene types. Therefore, irregularly shaped nanoparticles were created by utilizing a new generation method and the fullerene structures randomly sprinkle between Aluminium nanoparticles. Following this process, a sintering procedure was applied by using molecular dynamic simulations in order to obtain an atomistic model of a doped Aluminium matrix composite. In addition, adaptive common neighbour analysis (aCNA) was used to track the evolution of atomistic model morphology. Furthermore, the mechanical tests were carried out by using molecular dynamic simulations in order to understand the effect of the fullerene structures on the mechanical performance. Improvement in mechanical properties was achieved by adding fullerene to the aluminium matrix. Additionally, it has been observed that fullerene diameters have a significant effect in terms of yield and maximum tensile strength. This study proposes a new composite material with a mechanical performance created by a modelling approach that best represents real production technology.
