Fabrication and electromechanical performance of carbon nanotube based conductive membrane and its application in real-time multimode strain detection in composites

In this study, a flexible conductive membrane (CM) consisting of network carbon nanotubes is produced and the electromechanical behavior CM was studied experimentally gauge factor (GF) in 8–8.25 range. Then, multi-mode strain detection carried out composites using sensor. The embedded gradually at directions i.e. 0°, +45°, 90°, −45° between plies for real-time/in-situ monitoring. composite specimens are then cut star profile tested under tensile bending cyclic loading. There good reproducibility results mechanical response correlated perfectly with electrical resistance sensor however, each position showed distinct behavior. established that exhibited potential as in-situ monitoring can provide over large section unapproachable locations.
