Model for the Estimation of Partial Burst of Ripstop Electro-Conductive Fabrics

摘要

This paper presents the analysis of high current impulsive tests performed on electro-conductive fabrics. A ripstop conductive fabric is tested against 5.4 kA and 9.0 kA $8/ 20 mu mathrm{s}$ lightning currents. An equivalent circuit is used to represent the conductive interwoven yarns and the contact resistance between them. Using the proposed circuit and calculating the Specific Action applied at the woven sections and at the contact points, the change of phase and the loss of material on the conductive layer is described. Results show that the Specific Action can be used to estimate determined effects in materials as function of the excitation current signal.
