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]
Brian Milton is a British journalist, adventurer and aviation historian who made the first circumnavigation of the world in an ultralight aircraft in 1998. In the face of significant political, geographical, personal and physical hardships, he (with the aid of the pilot Keith Reynolds, a Qualified Flying Instructor from Kent) completed the 24,000 mile flight in 80 flying days, taking 120 days ...

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 ...

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.
“Today for the first time in more than a half century, the U.S. has returned to the moon.” Altemus had estimated that Odysseus had an 80% chance of successfully landing on the moon, citing ...
