ABSTRACT
CFRP
(carbon fiber reinforced plastic) is used extensively in aircraft and
spacecraft structures, because of its excellent mechanical properties. Ultrasonic testing,
which is used as a non-destructive testing technique for CFRP, requires a
contact medium. In contrast, eddy current testing does not require a contact
medium, and when used for CFRP testing it has advantages not available with
other techniques. CFRP is a laminate, with each layer being anisotropically
conductive, and the distribution of the induced eddy current is yet to be determined.
Here, to determine the eddy current distribution in the detection of flaws in
cross-ply CFRP (0°/90°) by using a cross-point probe, we performed an FEM (finite element method) analysis of electromagnetic fields. We investigated the nature of the flaw signals and the
differences in eddy current distributions between materials with and without
flaws.
