Laser Bondline Inspection Becomes Reality
Source: Composites World
Use of adhesive bonding to assemble composite structures is not new. Itís been widely used in every major end market the composites industry serves, ranging from automotive and marine to wind and defense. In high-performance applications like aerostructures, however, use of unitized, integrated structures has been limited by lack of confidence in the quality of adhesively bonded joints.

Further, although robust non-destructive inspection (NDI) technologies are available to verify flight-critical composites structures for certification, traditional NDI technologies are incapable of characterizing bond strength, which limits the acceptance of bonded joints in aerostructures. As a consequence, mechanical fasteners have remained the standard-bearer when it comes to reliably joining parts and providing damage arrestment.
