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]
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] It was developed by a team of scientists from California -based HRL Laboratories , in collaboration with researchers at University of California, Irvine and Caltech , and was first announced in November 2011.
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 ...
Internal structure of a 'closed-graphitic-shell' aerographite (SEM image)Aerographite is a synthetic foam consisting of a porous interconnected network of tubular carbon. . With a density of 180 g/m 3 it is one of the lightest structural materials ever crea
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 .
Stuff Matters: Exploring the Marvelous Materials That Shape Our Man-Made World is a 2014 non-fiction book by the British materials scientist Mark Miodownik. The book explores many of the common materials people encounter during their daily lives and seeks to explain the science behind them in an accessible manner.
The ultralight backpacking community has begun to use Tyvek for the construction of extremely light yet durable backpacks. [26] [better source needed] In 2012, The Open Company released a foldable city map made of one of the stiffer variants of Tyvek. [27] Increasingly, reused Tyvek material is being used by home crafters.
