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]
In this way, the process enables large free-standing 3D lattice materials to be formed quickly and scalably. The template was then coated with a thin layer of metal by electroless nickel plating, and the template is etched away, leaving a free-standing, periodic porous metallic structure. Nickel was used as the microlattice metal in the ...
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 .
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.

Val Kilmer is stepping back into the spotlight. The "Top Gun" actor made a very rare public appearance on Monday at a charity basketball game, where he wore a button-down shirt painted with the ...
By September 2017, the prototype had flown 10,000 mi (16,093 km) in a series of flights of at least 30 mi (48 km) each. The first pre-production aircraft was flown in October 2017. [1] [5] The design is intended for the FAR 103 Ultralight Vehicles category in the United States and the Basic Ultralight Aeroplane category in Canada. The American ...
