Research on Block Modeling and Electromagnetic Nondestructive Testing Method for Plain Weave CFRP

Abstract

Aiming at the characteristics of electrical impedance anisotropy of plain weave carbon fiber reinforced composites(CFRP), a new discrete modeling method is proposed in this paper. The structure of plain weave CFRP was characterized by a double-coil rotation sensor, and its surface cracks were detected, and experiments were designed to verify the accuracy of the simulation model.
