Abstract: This paper presents the overview of previous studies on
the eddy current testing of Carbon Fiber Reinforced Plastic (CFRP)
composites. CFRP is composed of many unidirectional carbon fiber/epoxy plies
stacked together, thus it has laminated structure and inhomogeneous nature.
Eddy Current Testing (ECT) is an efficient and non-contact Nondestructive
Testing (NDT) technique for conductive materials. The electrical
conductivity of carbon fibers can be utilized by ECT system for fiber
texture mapping and detection of defects that can cause the conductivity
change. Recently a lot of attention has been paid to the electromagnetic
properties characterization of CFRP material, fiber texture and defect
detection, as well as the ECT technique enhancement. In this paper we will
give the detailed information and results of these research works. In
addition this paper also summarizes the available numerical simulation
methods for the electromagnetic modeling of CFRP materials, and the
calculation of eddy currents and ECT signals.
