According to the scientists, the light, cheap and flexible aluminium solution can be used to protect fences, buildings, ammunition dumps and containers from impacts and explosions, from small stones to metal-piercing projectiles and bombs.
The technology was developed by the University and the Norwegian Defence Estates Agency (NDEA). According to the researchers, they created computer models for design, and experimented with alloys, dimensions and construction.
The solution is made from a type of double panel filled with a heavy substance such as dirt, sand, gravel or small stones.
The panels are pieced together from aluminium shapes that have cavities in them. According to the developers, these aluminium pieces can be produced easily by extruding them through a mouthpiece to give the desired cross-section.
The solution is said to be easier to move than steel or concrete structures. The heavy material can be drained from the bottom when the panel needs to be unmounted and moved to another area.
Researchers are currently working to develop light plates made from aluminium foam that could provide more applications.
