Strong and uniform carbon nanotube (CNT) fibers with tensile strength around 1.2 GPa were prepared from vertically aligned CNT arrays, and their mechanical properties were studied using a wide range of tensile strain rates. The cyclic load/unload process, polarized Raman measurements, and fiber frac...
