A. Lemartinel, M. Castro, O. Fouche, J.C. De Luca, J.F. Feller, Impact and strain monitoring in glass fiber reinforced epoxy laminates with embedded quantum resistive sensors (QRSs), Compos. Sci. Technol. 221 (2022) 109352. doi:10.1016/j.compscitech.2022.109352.

Highlights

• CNT-based Quantum Resistive Sensors are embedded in and between plies of GFRP.

• QRS signal is in phase with the impact load and proportional to its intensity.

• Amplitude of electrical signal is related to location and vicinity to the impacted zone.

• Health state of GFRP is monitored by QRS during impact/cyclic bending sequences.
