Resumen:
Open-cell Al foams were produced by the replication casting technique in
three different pore sizes. All produced foams were physically
characterized, determining their relative density, porosity, and pores
per inch, as well as their mean pore surface area and diameter.
Permeability tests were carried out by means of the injection of a
highly pressurized gasoline additive at room temperature and 200 degrees
C, at pressures of up to 25,000 psi. The structural capacity of the
studied specimens to conduct fluids at these critical experimental
conditions was assessed by means of compression tests in order to
determine their mechanical properties after the permeability tests,
e.g., energy absorption capacity, Young's modulus, and plateau stress.
It was found that the produced open-cell Al foams were able of
conducting the gasoline additive at critical flow conditions of pressure
and temperature, without suffering important physical nor structural
damage.
