The use of sandwich structures provides exceptional strength to weight and bending stiffness to weight properties. These are attained by using thin dense skins which sandwich a low-density core. To date such systems have concentrated upon Al foam cores which themselves demonstrate exceptional impact-energy absorption capabilities as demonstrated by uniaxial compression tests. A number of gaps exist in the knowledge of this field, in particular:

The optimum core structure in terms of intrinsic mechanical properties of the alloy and density.
The influence of skin properties upon bend strength and beam collapse.
The influence of the skin upon contact damage.
The residual strength of the structure following contact, be it impact or quasi static.
The project will seek to redress these deficiencies.
