Researchers at the Massachusetts Institute of Technology have developed a lightweight structure that snaps together with tiny blocks that resemble children's construction toys. The researchers said that the new materials can completely change the assembly of aircraft, spacecraft, and even larger structures such as embankments and flood protection embankments.
The construction of new methods to describe this week appeared in the "Science" magazine, co-authored by the postdoc, Zhang Zhicheng and MIT Institute of Bit and Atomic Center Nierchen Shen Feide in a paper.
The structure of Zheshenfeld's metaphor, it is composed of tiny, identical, interlocking pieces of chain mail. The part, based on a new geometric shape, is a long developer with zheshenfeld, forming a structure that is 10 times harder for a given weight than existing ultralight materials. However, this new structure can also be easily disassembled and reassembled, such as repairing damage, or recycling the components for a different configuration.
Individual parts can be mass-produced; Jerzenfeld and Cheung are developing a robotic system to assemble wings, aircraft fuselage, bridges or rockets and many other possibilities.
Combining three new research areas in the field of design, Gershenfeld said: Fabric composites, honeycombs (with porous cells) and additive manufacturing (such as 3-D printing, deposition, and not the removal of the structure of the material are established ).
With traditional composite materials as a continuous unit now used everything from golf clubs and tennis racquets to the manufacture of Boeing's new 787 aircraft each piece. Therefore, the manufacture of large structures, such as aircraft wings, requires a large number of factories, where fiber and resin can be wound and partially thermally cured as a whole, minimizing the number of separate parts that must be added in the final assembly.
What's more, when traditional composites emphasize the breakthrough point, they tend to suddenly and massively fail. However, the new modular system tends to fail only incrementally, which means it is more reliable and can be more easily repaired, the researchers said.
Convenient folding for long battery life.
