Low Frequency GFRP Imaging with Variable Aperture TFM
e-Journal of Nondestructive Testing, 2023 Graphite or glass fiber reinforced polymer (GFRP) inspections are usually made with a zero-degree linear scan (L-scan) (1). Total focusing may not be applicable for some anisotropic materials, but in some cases, TFM may increase the ultrasound imaging ...
