DESIGN OF GENERAL LATTICE STRUCTURES FOR LIGHTWEIGHT
observed for ultralight aerogels a nd carbon nanotube foams with stochastic architecture. We attribute We attribute these properties to structural hierarchy at the n …. That's the section on processing of the honeycombs and the foams and the lattices. So there's a variety of different techniques that people have developed for making these kinds of materials. And I thought it'd be useful to just describe some of the techniques.

Mechanical Properties of Laser-Sintered-Nylon Diamond Lattices
An overview of the mechanical properties of foams and periodic lattice materials Norman A. Fleck Cambridge University Engineering Department, Trumpington St., Cambridge, CB2 1PZ, UK Abstract Metallic foams and lattice materials are compared in terms of properties and underlying deformation mechanisms. Lattice materials can be made to possess mechanical properties which are similar to, ….
Man and nature both exploit the remarkable properties of cellular solids, by which we mean foams, meshes and microlattices. To the non-scientist, their image is that of soft, compliant, things: cushions, packaging and padding..
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. . properties of PU foams [2,5]. The data are largely dependent on foam producer, as used The data are largely dependent on foam producer, as used substrates and production technology decide on intrinsic structure and foam density, and.
