| Abstract Scope |
Currently, nanocomposites offer new technologies and business opportunities for all sectors of the industry. When designed for equipment that can withstand high deformation rates, nanoscale reinforcements can improve engineering polymers, which emerge as the best matrix component alternative for the development of nanotechnologies that assist the combatant during their action. This work evaluates the dynamic behavior of a polycarbonate reinforced with graphene oxide (PcGO). This study aims to verify if the methodology adopted for the dispersion of the 2D material, GO, in the polycarbonate (PC), promotes to it, values of dynamic tension higher to those found for the materials produced with virgin polymers. Dynamic analysis with the aid of a Split Hopkinson Pressure Bar was performed with three different strain rates. The results showed that the solution mixing de 1 wt. (%) of GO dispersed in the PC (PcGO) promotes values dynamic yield limit higher to PC as received. |
