The name of the world lightest structural material
known to science as of today is Metallic micro lattice. It is a synthetic
porous metallic material. It consists of ultra-light metal foam.The credit
goes to the scientists from California- based HRL laboratories. The prototype
shown in the picture is made out of nickel-phosphorous alloy. It is one of the
world changing innovations. The application of this metal will be widely in
automobile and aerospace. It has the density as low as 0.9 Kilogram per
meter-cube. The composition of metallic micro-lattice is of network of
interconnecting hollow struts.
The inspiration behind this innovation comes form the
close examination of bone which consists of hollow honey comb structure. The
meal based micro-lattice structure is significantly less dense than the rarest
aerosol,ultralight foams. It exhibits high strength and high ability to absorb
energy which make them their application in making shock absorbers.
