Sea sponges inspire super strong material for more durable buildings | The team studied how the double lattice structure – seen in the skeleton of a sponge demonstrated not only impressive strength, but also auextic behavior – the ability to contract when compressed.
All those sea sponges that live in deep oceans have a secret: their light lattice-like forms are astonishingly stiff and strong. Inspired by these fascinating creatures, researchers at Australia's RMIT University have developed a new structure to make significantly stronger materials for more…
The team studied how the double lattice structure – seen in the skeleton of a sponge called Venus' flower basket – demonstrated not only impressive strength, but also auextic behavior – the ability to contract when compressed. The entire skeletal tube of Euplectella aspergillum (left), a magnified view highlighting its regular lattice-like structure, and the pattern of alternating open and closed cells "We’re developing a more sustainable building material by using our design’s unique combination of outstanding auxeticity, stiffness, and energy absorption to reduce steel and cement usage in construction," Ma explained.
