Abstract
Electrically conductive nanocomposites have incredible potential for integrated structural damage identification when employed as matrices in structural fiberreinforced composites. That is, because nanocomposites could consist of wellconnected nanofiller networks with conductivity, matrix damage that severs the nanofiller network will manifest as a conductivity loss. Locating damage-induced conductivity losses is therefore tantamount to locating damage. In this regard, welldispersed nanofiller networks can be thought of as pervasive and integrated sensor networks. This research explores this approach by utilizing electrical impedance tomography (EIT) to locate impact damage of a glass fiber/epoxy laminate plate manufactured with carbon black (CB) filler. It is found that EIT can successfully locate impact damage thereby demonstrating the potential of conductivity-based damage identification in structural composites with nanocomposite matrices. doi: 10.12783/SHM2015/211
