Abstract
Many structural and safety hazards, especially in the aerospace and automotive industries, are invisible to an outside observer. More automotive and aerospace manufacturers are becoming more focused on composite materials, where many parts are now bonded.As of now, there are few feasible methods of detecting defects within the bond layer without implementing destructive evaluation. Non-contact methods of non-destructive evaluation (NDE) for bond layer inspection could allow for faster manufacturing, quality assurance, and cheaper manufacturing. The research conducted explored two methods of non-destructive evaluation (NDE) for structural health monitoring (SHM). One, a hybrid method, employs a piezoelectric lead zirconate titanate (PZT) - scanning laser Doppler vibrometer (SLDV). The other, a fully non-contact method, employs two air coupled transducers (ACT-ACT). It was found that both of thesemethods could detect damage to a specimen, and each method has different benefits. More research must be conducted to determine the full extent to which each method can analyze a specimen.
