Abstract Scope |
Aluminum alloys have always been considered essential materials for engineering applications. Properties such as low density, high ductility, thermal and electrical conductivity characteristics as well as good mechanical resistance make this metal suitable for a variety of industries. Aluminum foam is used when a light metal with a great amount of porosity is necessary and during the last decade, some research has been carried out regarding the energy absorption of this kind of material. In this work, an aluminum foam was produced and morphologically characterized by SEM analysis. Ballistic tests were performed with high velocity 7.62mm ammunition, in order to determine the amount of energy absorbed by the material. Results were compared with bulk aluminum alloy, and it was observed a higher specific energy absorption by the aluminum foam. It was proposed that such behavior might be associated with pores closing after the ballistic test. |
