Abstract

Abstract : Damage inside a carbon fiber reinforced polymer (CFRP) piece can be imaged and analyzed by the ultrasound generated by acoustic micro‐imaging tools. Imaging may be carried out to find cracks and other gap‐type anomalies that occurred during fabrication, as a result of testing, or during service. Even if the vertical extent of a gap is a tiny fraction of a micron, damage within the CFRT appears in the acoustic image. This is one of the capabilities that makes acoustic micro‐imaging complementary to X‐rays Abstract : Damage inside a carbon fiber reinforced polymer (CFRP) piece can be imaged and analyzed by the ultrasound generated by acoustic micro‐imaging tools.
