Abstract

This paper presents the theoretical and experimental results on the electrical resistance property and crack behavior of carbon nanotube (CNT)-based polymer composites. First, the characterization of the electrical properties is described. An analytical model for predicting the electrical conductivity of CNT-based composites was developed, and electrical conductivity measurements were also performed. Next, the strain sensing behavior is examined. Tensile tests were conducted and the electrical resistance was measured during the tests. An analytical model was also developed to describe the electrical resistance change due to strain. Finally, the crack behavior and crack sensing capability are discussed. Tensile tests were performed on single-edge cracked plate specimens, and the electrical resistance of the specimens was monitored. An analytical model was also developed to predict the resistance change resulted from crack propagation. In addition, the fracture properties were evaluated in terms of the J-integrals using an elastic-plastic finite element analysis.
