摘要: Carbon nanomaterials have gradually demonstrated their superiority for in-line process monitoring of high-performance composites. To explore the advantages structures, properties, as well sensing mechanisms, three types carbon nanomaterials-based fiber sensors, namely, nanotube-coated fibers, reduced graphene oxide-coated and were produced used key elements embedded in fabrics manufacturing fiber-reinforced polymeric Detailed microstructural characterizations performed through SEM Raman analyses. The resistance change smart fabric was monitored real-time composite manufacturing. By systematically analyzing piezoresistive performance, a three-stage behavior has been achieved registering resin infiltration, gelation, cross-linking, post-curing. In first stage, incorporation expands packing structure various media introduces different levels increases resistance. second concomitant shrinkage dominates attenuation after reaching maximum level. last diminished effect competes with disruption conducting network, resulting continuous rising or depressing
