The mechanical properties and stability of a new class of carbon nanostructure, diamond nanotori (DNTs), have been investigated by molecular dynamics simulations. Simulations indicate that DNTs are stable, even for tori with very small radii, and that they have tensile strengths near that of carbon nanotube tori (tori built from carbon nanotubes, CNTTs). The possible use of these novel nano-materials in high-strength, light-weight materials will be discussed based on the simulation results. The simulations suggest that DNTs have tensile strengths approximately 10 times that of steel, and if woven into chains or chain-mail these novel materials could be used in very demanding applications like NASA's proposed space elevator. The yield strength as a function of strain rate, tori size, and toroidal macro-topology will be discussed. These results will be compared to results obtained by other for CNTTs.
