The present research paper analyzes the behavior related with the impact toughness and the fracture mechanics displayed by new composite materials. These materials were manufactured by powder technology, based on recycled PET, as a polymer matrix, reinforced with respectively 10 and 30 wt% zinc metal particles. The necessary test specimens for isothermal sintering were prepared and exposed at 256°C for 15 minutes periods. These preliminary specimens permitted to determine the strain intensity factor around a crack, using the Peterson´s and Irwin´s models, and using the Griffith criterion in order to find the value of liberated energy. Therefore the best results were obtained when the content of metallic particles were increased because the material improve its mechanical properties like resistance and tenacity.
