Strong bundles based on carbon nanotubes

Long bundles of defect-free carbon nanotubes can exhibit exceptionally high strength.

The ‘ultimate strength’ of materials is a fascinating topic. Griffith contributed groundbreaking experiments on the fracture strength of glass in the 1920s, and accurately predicted the ultimate strength of glass by extrapolation of his dataset on deliberately introduced larger cracks to very small cracks and to ‘no cracks’. He developed the theory of fracture mechanics that has been extended for predicting the ultimate strength of materials.
