Design and Comparison of Directional Transmit to Differential Receiver (Tx-dRx) Eddy-Current Probe for In-Line Monitoring of 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
