Aluminum alloys are consider as important materials for engineering applications due to properties such as low density, high ductility and mechanical resistance. Therefore, the use of this metal is suitable for a variety of industries, for instance, the aeronautic and energetic. The foam of aluminum is used when a lighter metal with a great amount of porosity is necessary and during the last decade some researches have been done about the energy absorption of this kind of material. In this work aluminum foam was evaluated for ballistic protection application. The morphologic aspect of the fracture was characterized by optical and electronic microscopy. The results revealed a high specific energy absorbed when compared with a high strength dense aluminum plate, commonly used in multilayer armor systems. Such behavior was associated with the closing of the pores of the structure after the ballistic test, observed by microscopy.
