Here we weighed the specimen in order to test the porosity using the density of aluminum in the calculation. We found it to be about 85% porous.

This sample was about 95% Porous according to our measurements.

Here we wanted to test how much energy the small cell foam would be able to absorb upon compression of 1,000 lbs loading.

We found the small cell foam to have about 300 in*lbs/in^3 of energy absorbed per volume of metal foam.

Starting at the left, Small Cell Specimen before compression, Small Cell Specimen after compression, and finally a large cell sample of 3 inches height rather than a 1 inch cube.

Here we used an air compressor to mimic a jet engine sound frequency and then had a microphone measure data when compared with a control and one sample with large cell pores and another with small cell pores. We found the small cell aluminum foam to dampen sound significantly. It outperformed current sound insulation in use today.
