GPa

The group created the ADNRs by compressing the carbon-60 molecules to 20 GPa, which is nearly 200 times atmospheric pressure, while simultaneously heating to 2500 Kelvin.

Nano Material Harder than Diamonds | Impact Lab 2005

With a theoretical tensile strength of 100 gigapascals GPa which is ten times that required to form diamonds, or just 280 GPa’s less then the pressure at the core of the Earth.

Self-assembled Nano-circuit boards with DNA Origami and Carbon Nanotubes 2008

James S. Schilling, Ph. D., professor of physics in Arts & Sciences at Washington University in St. Louis, and Mathew Debessai — his doctoral student at the time — discovered that europium becomes superconducting at 1.8 K (-456 °F) and 80 GPa (790,000 atmospheres) of pressure, making it the 53rd known elemental superconductor and the 23rd at high pressure.

You are correct with the linear mass density figure, but start with a Carbon Nanotube material that has a specific strength of 40 GPa-cc/g, and see how much cable is required to carry a 20 ton climber… you'll be surprised, as I was a few years ago.

Black Hole Drive Could Power Future Starships | Universe Today 2009

I understand that the kg/cm2 unit is now deprecated and that tensile strength is more commonly quoted in GPa (giga pascals) but how many kg/cm2 is equal to a GPa?

Space Elevator Still At Ground Floor 2008

The measured tensile strength of chrysotile fibers has been reported in the range 1. 1-4.4 GPa (160,000-640,000 psi).

Geology of asbestos 2007

The inherent tensile strength of a single asbestos fiber, based on the strength of Si-O-Si bonds in the silicate chain, should be near 10 gigapascals (GPa) (1.45 x 106 pounds per square inch [psi]).

“The synthesis was possible due to a unique 5000-tonne multianvil press at Bayerisches Geoinstitut in Bayreuth that is capable of reaching pressures of 25 GPa and temperatures of 2700 K at the same time,” Dubrovinskaia told PhysicsWeb.
