Which material has the most tensile strength?
The largest strength material is the carbon nanotube. It is also the strictest known material with an extremely high elastic module, which means that it is not easy to stretch. Carbon nanotubes can be visualized as graphene leaves curled into the cylinders only about the width of the molecule.
These cylinders may have individual walls (SWNT or one -walled carbon nanotubice) or more walls (MWNT or multi -walled carbon nanotrubice). Multibod carbon nanotubes were measured as material with the most in tensile strength of all, measuring at 63 GPA (Gigapascals) for atomic testing, significantly below the theoretical maximum of 300 GPa. Scientists have not yet been able to produce this strength in mass materials, even if the work lasts and seems likely to success. Nanotruby nanotubes fiber with a pile was created with a tensile strength of 1.6 GPa, which is the most touches of nsile of any fiber, natural or artificial, via the order size. Another improvement about another order seems to be in the nextSeveral decades credible. The carbon nanotrub fiber is so strong that the fiber cord in the length of 50,000 km (31,070 miles) could spread from the Earth's surface to geosynchronous orbit and would not break. This concept is known as a cosmic elevator.
In May 2007, scientists financing the US Navy managed to produce carbon nanotubes with a length exceeding 2 mm, the longest. The ratio of the length of these nanotubes is approximately 900,000 to 1 .. Navy is obviously interested in fibers with the most possible strength, because it uses ropes for a number of purposes such as anchoring, fasteners, etc. Thicker fibers would allow immersed equals (more remote) more relatively, and be more relatively, and be more relatively, and be more relatively, and be relatively, and be republics and be republics, and it could.Stoed to their basic stations, relevant in the Japanese Right of $ 15 million, among the most advanced in the world that has recently been lost in a strong storm. Thus, fibers with the most tensile strength would increase our ability to explore ocean floors.
Similar advantages could spread to all areas of engineering and design. Bridges could be much stronger if carbon nanotubes were more accessible. At present, it costs hundreds or thousands of dollars per gram, but costs have declined exponentially in recent years.
