Structural health monitoring of carbon-material-reinforced polymers using electrical resistance measurement

Abstract

This paper presents a review of structural health monitoring techniques for carbon-based materials and structures. Based on the piezoresistivity of carbon, elastic deformation and the failure of carbon structures are visible by monitoring the electrical resistance. Carbon structures have an in-situ real-time self-sensing capability, eliminating the need for additional sensors. Numerous researchers have investigated the electromechanical properties of carbon materials by conducting experiments, numerical analyses, and simulations. In addition, the electrical conductivity of carbon is reinterpreted as an electrically equivalent circuit in order to investigate orientation-dependent sensing.
