Abstract

In this paper, our work on studying the tensile strength of single-walled carbon nanotube (SWCNT) bundles, their fatigue, and time-dependent behavior are presented. Results from tensile testing of SWCNT bundles enable us to interpret the strength distribution of SWCNTs. The fatigue behavior of unidirectional, aligned SWCNT rope reinforced epoxy composite under tension-tension cyclic load was studied. Patterns of crack propagation under tension in a SWNT were also studied by molecular mechanics simulations. In addition, we will also present results of creep rupture tests of SWCNT bundles. Small bundles of SWCNT were tested under constant displacement until failure. Failure modes were examined by scanning and transmission electron microscopy. Finally, we will present a life prediction scheme for SWCNT fatigue based and molecular simulation and kinetic fracture concept.
