Eddy current testing; non-destructive evaluation; probe optimisation; uncured composite; automated fibre placement

This research examines the creation and evaluation of directional eddy current probes designed to identify in-plane waviness in uncured carbon fibre reinforced polymers (CFRP). A new finite element modeling technique was used to precisely replicate current density distortions caused by waviness. A sample made from uncured IM7/8552 prepreg with in-plane waviness on its top layer was produced
