The aim of this research was to check the changes on the mechanical properties of poly(butylene adipate co-terephthalate)/poly(lactic acid) (PBAT/PLA) polymeric blend, after radiation process in different radiation doses. The irradiation was performed in an electron beam accelerator, with 1.5 MeV of energy and 25 mA electric current. The samples were irradiated with doses of 5, 10, 15, 25, 50, 65 and 80 kGy. Irradiated and non-irradiated samples were characterized by Izod pendulum impact resistance and tensile strength at rupture. The results showed an increase of 44% in relation Izod impact resistance at dose of 65 kGy. However the module of elasticity decreased 56% and tensile strength at rupture decreased 55% at the same radiation dose. In relation of elongation was not observed significate alterations caused by electron beam irradiation. It can be concluded that irradiated blend could be used to make environmental friendly products, which could absorb impact energy.
