Quality Assurance Conceptsfor Adhesive Bondingof Aircraft Composite

Structures by Extended NDTComBoNDT project meets the European Aviation Safety Agency (EASA) certi�cation requirements for structural bonding. The extended non-destructive techniques used in ComBoNDT aim at establishing reproducible and reliable NDT tools to ensure the reliable strength of joint structures.

The overall objective of ComBoNDT is to develop a quality assurance concept for adhesive bonding of load-critical CFRP primary aircraft structures, which is applicable within the whole life cycle of the aircraft to overcome the current limitations regarding certi�cation of composites.
