Analysis of the porosity structure of open-cell aluminum metallic foams and its influence on the mechanical properties

Abstract

The field of materials is present in all aspects of our daily and professional lives, so that every day we continue to create, innovate and improve new elements more and more frequently. The quality of a material depends on several factors and characteristics at the level of engineering, industrial production, etc. For these reasons the present project is established, which aims to carry out the analysis of the porosity structure of aluminum metallic foams obtained by means of the experimental infiltration method, using soluble sodium oxide (Na2O) preforms, unlike previous ones. methods in which salt (NaCl) is used. This type of material is used for absorption of impact energy, vibrations and sound, as well as a thermal insulator in some applications. The appropriate protocol for the generation of these foams is determined, with the materials and equipment, with their optimal parameters, dimensions and graphics. The characterization of the pore is carried out, with the mechanical properties of compression and impact absorption, to determine the relationship with the pore size through tests, equations, graphs and tables of values of each element. The specimens to be generated will be of two types: 3mm pore size and 5mm pore size. It is concluded that the 3mm specimen has better energy absorption capacity than the 5mm specimen.
