Response of Carbon Nanotube (CNT) Ply Subjected to a Pulsed Magnetic Field

Abstract

In this study, the possible deformation of a single Carbon Nanotube (CNT) ply subjected to a pulsed magnetic field was investigated. In all tests the capacitor bank was charged to 6kJ of energy. A Photon Doppler Velocimetry (PDV) system was used to measure velocity or displacement of the CNT ply during the experiments. The resistance of the CNT ply was measured using four-point probe technique before and after the experiments. Preliminary results show that the single CNT plies do not permanently deform in response to the pulsed magnetic fields. However, they can be displaced, either by themselves a small amount (0.6mm) or by a large amount using a driver material. Also, the resistance of the CNT plies may increase or decrease depends on the lay-out (i.e., yarn) and current flow directions.
