Title: | Carbon nanotube-decorated glass fibre bundles for cure self-monitoring and load self-sensing of FRPs | Authors: | Su, Y Xu, L Zhou, P Yang, J Wang, K Zhou, LM Su, Z |
Issue Date: | Oct-2021 | Source: | Composites communications, May. 2021, v. 27, 100899 | Abstract: | Extra to serving as the reinforcement in polymer-based composites, glass fibres (GFs) are decorated with dense and uniform carbon nanotubes (CNTs) via chemical vapor deposition at a low CNT growth temperature (500 °C). The hairy CNT-decorated GF bundles measure the dynamic variation in electrical resistance using CNT-formed piezoresistive networks in the bundles, with which the resin flow front and cure progress of epoxy during fabrication are self-monitored by the composites. The bundles also precisely sense in-service loads applied to the composites, with a gauge factor as high as 30.2. Without intrusion to the original composites from sensors and sensor-associated electrodes/cables, the CNT-decorated GF bundles shed light on the use of nanocomposite-driven fibre decoration towards development of new functional composites. | Keywords: | Carbon nanotubes Cure monitoring Fibre decoration Nanocomposites Structural integrity monitoring |
