Ultralight materials are solids with a density of less than 10 mg/cm 3. Ultralight material is defined by its cellular arrangement and its stiffness and strength that make up its solid constituent. They include silica aerogels, carbon nanotube aerogels, aero graphite, metallic foams, polymeric foams, and metallic micro lattices. [1]
A metallic microlattice is a synthetic porous metallic material consisting of an ultra-light metal foam. With a density as low as 0.99 mg/cm 3 (0.00561 lb/ft 3), it is one of the lightest structural materials known to science. [1]

They offer both a linear regime and a nonlinear super-elastic deformation mode a modulus an order of magnitude greater than for an ultralight material (12.3 megapascals at a density of 7.2 mg per cubic centimeter). Bulk properties can be predicted from component measurements and deformation modes determined by the placement of part types.
When the material is critically heated, the liquid evaporates and the bonded, cross-linked macromolecule frame is left behind. The result of the polymerization and critical heating is the creation of a material that has a porous strong structure classified as aerogel. [14] Variations in synthesis can alter the surface area and pore size of the ...
The Hawk line of ultralight aircraft was introduced at Sun 'n Fun, Lakeland, Florida, in March, 1982. The Hawk was the first fully enclosed ultralight, the first with fully strut-braced wings, three-axis controls, a steerable nose or tail wheel and wing flaps .
Barry Hill Palmer (born November 10, 1937) is an American aeronautical engineer (UC Berkeley, 1961), inventor, builder and pilot of the first hang glider based on the Rogallo wing or flexible wing. Palmer also designed, built and flew the first weight-shift ultralight trike aircraft.
