Carbon, as we all know is one of the strongest materials in the world, much because of its covalent bonding between atoms. This chemical property makes it the strongest and the lightest material known to man kind (yeah diamonds are carbon compounds too).
Take a look at this structure built by university of Stuttgart! Isn’t it amazing? Who’d believe that it was built by robots, but it was. Coming to the structure, you’d find that the more complexly woven the carbon fibers are, the stronger the structure will be The carbon fiber we are referring to here, consists of very thin filaments of carbon bound together with plastic polymer resin by heat, pressure or in a vacuum. The resulting composite material is both strong and lightweight.
