According to our information, every substance in this world we know about is cuttable, even the diamonds to date. However, some engineers have now claimed to develop a material naming “Proteus” which is the first manufactured uncuttable material. The compound is developed with porous aluminium and ceramic therefore it has lighter weight than steel and however is going to withstand any grinder.
According to researchers at Durham University in England and Germany’s Fraunhofer Institute, Proteus withstand cutting by revolving the cutting tools against themselves and blunting them. The material is developed with an aluminium matrix (aluminium foam) implanted with ceramic spheres and it is 15-per cent less dense than steel which makes it perfect for applications such as lightweight armour.
As the means of cutting bites into the aluminium, it experiences extreme intense vibrations when it strikes the ceramic spheres. This vibrancy induces the tool to begin bouncing, consequently “dulling” its cutting edge. Moreover, because the ceramic is a strike, fine dust particles fill in the matrix. The interatomic forces between the grains rise in proportion to the quantity of energy used which makes the material even harder the faster the tool spins.
Stefan Szyniszewski, Durham’s Assistant Professor of Applied Mechanics stated that,
“The force and energy of the disc or the drill are turned back on itself, and it is weakened and destroyed by its own attack.”
“Essentially cutting our material is like cutting through a jelly-filled with nuggets. If you get through the jelly, you hit the nuggets, and the material will vibrate in such a way that it destroys the cutting disc or drill bit.”
Furthermore, Proteus is effectual against the drills, angle grinders, and other traditional cutting tools as well as useful against high-pressure water jet cutters. In this case, the material operates differently in that the rounded surfaces of spheres disperse the water weakening the jet.
In the security and safety sectors, the researchers watch possible applications. Armoured means of transportation are possibly lighter and stronger or locks could demonstrate invulnerable to cutting tools. It could also be utilized to create protective equipment for those who utilize cutting tools, Ironically.
Presently, Proteus is patent-pending, and the team of researchers is finding manufacturing partners for the marketing of the material. In case you are concerned in the technical details, they have issued their research in Scientific Reports.
