Abstract
A non-destructive testing (NDT) system based on a superconducting quantum interference device (SQUID) is used for detecting the electromagnetic properties of three-dimensional (3D) braided composites. Samples with artificial defects are detected via artificial neural network and the flux imaging methods; the results compared well. Experimental results indicate that the SQUID-based NDT technique is far more advanced and practical for three-dimensional (3D) braided composites.
