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]
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.
Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene ( UHMWPE , "Dyneema") laminated between two sheets of polyester .
Altadena's eclecticism and independent spirit drew residents. After the Eaton fire, they face a crossroads over whether to stay and rebuild their community, or leave.
For the first time in two decades, the Food and Drug Administration (FDA) has approved a new class of medication that provides an alternative to addictive opioids for patients looking to manage ...
Mulalo Doyoyo FRSA (13 August 1970 – 11 March 2024) was a South African engineer, inventor, and professor. [1] [2]Doyoyo was a researcher in applied mechanics, ultralight materials, green building, renewable energy, and other fields of engineering.
