Abstract

This paper introduces a hybrid composite material, where the structural carbon fiber tow is transformed into a piezoresistive damage localization sensor network, and the structural glass fiber operates as electrical insulation. The piezoresistive damage localization sensor network consists of an array of carbon fiber tows, each with increasing resistance, connected in parallel. Including a second orthogonal array enables accurate 2D damage localization of large-area composites. Impact tests were conducted, finding the sensor network able to reliably determine the location of damage in both orthogonal directions, pinpointing the exact location of damage. This illustrates a capability for in situ monitoring of large-area composites throughout the life cycle of the structure.
