A State-of-the-Art Review of Non-Destructive Testing Image Fusion and Critical Insights on the Inspection of Aerospace Composites towards Sustainable Maintenance Repair Operations

Non-destructive testing (NDT) of aerospace structures has gained significant interest, given its non-destructive and economic inspection nature enabling future sustainable maintenance repair operations (MROs). NDT been applied to many different domains, there is a number such methods having their individual sensor technology characteristics, working principles, pros cons. Increasingly, approaches have investigated alongside the use data fusion with aim combining sensing information for improved performance more informative structural health condition outcomes relevant structure. Within this context, image particular focus. This review paper aims provide comprehensive survey recent progress development trends in NDT-based fusion. A aspect included work providing critical insights on reliable composites, weight-saving potential superior mechanical properties composites support airworthiness. As integration composite materials rather limited current literature, some examples from non-composite are also presented as means into potential.
