This paper presents a combined numerical-experimental study on the loading ratedependent fracture behavior of cracked carbon nanotube (CNT)-based polymer composites under tension. Tensile tests at various loading rates were conducted on single-edge cracked plate specimens of CNT/polycarbonate composites. The electrical resistance change of the composite specimens was utilized to capture the crack behavior during the tests. An elasticplastic finite element analysis was also employed to determine the fracture properties by means of the J-integral. In addition, scanning electron microscopy (SEM) observation was implemented to assess the fracture mechanisms of the CNT-based polymer composites under the different loading rates.
