Abstract
- We performed the tensile test of an individual carbon nanofiber (CNF) inside a scanning electron microscope. The mechanical testing system was installed in a scanning electron microscope (SEM). The nano-manipulator was set up in the SEM, and the force sensor, which is formed as a cantilever, was mounted on the nano-manipulator. Then, the force sensor can be controlled by using the nano-manipulator. The CNFs were dispersed on the transmission electron microscope (TEM) grid, and the both end of the CNFs were welded on the TEM grid and the tip of force sensor by exposing electron-beam of the SEM. The tensile test of the CNFs was performed by controlling the nano-manipulator. The load response during the tensile test was obtained by force sensor. Stess-strain curve was obtained from force-displacement curve of CNF after tensile test. The elastic modulus of CNFs was calculated at ~12.5 GPa.
