Abstract
A system and method for determining fiber orientation within a layered composite using an eddy current probe is discussed. The eddy current probe includes an array of coils that are excited such that an effective pole of the end effector of the probe moves in a ring pattern. The eddy current probe is moved across the surface of a part such that a two-dimensional scan of the part is generated, analogous to a C-scan in ultrasonic testing. The eddy current probe is able to be used to determine the fiber orientation of a layered composite material by scanning at a single point on the material. The eddy current data is able to be fused with data from an ultrasonic transducer to produce a comprehensive view of the part.
