Fabrication and compressive properties of low to medium porosity closed-cell porous aluminum using PMMA space holder technique

In recent years, closed-cell porous Aluminum (Al) has drawn increasing attention, particularly in the applications requiring reduced weight and energy absorption capability such as in the automotive and aerospace industries. In the present work, porous Al with closed-cell structure was successfully...
