Why choosing Q-810 Shearography NDT? • Repeatable measurements • Fast inspection -> field-of-view of 20 cm x 20 cm -> Up to 1 m² inspected/minute • Detection Capabilities on Composite Materials -> Disbonds, delaminations, wrinklings, etc • Tunable vacuum excitation • Option internal/external heat frame Slide 9 | Kim Hallqvist | Q-800 September 2009 Super quality services| sqs ppt-Q 810 Super quality services| sqs-001 2016

The basic principles of the measurement method are interferometry and correlation techniques • Interferometry is determination of fractional relative phase difference between light waves traversing different paths. Phenomena which can be measured are those which influence the phase of the light beams. In practice this is e. g. surface deformation Slide 10 | Kim Hallqvist | Q-800 September 2009 Super quality services| sqs ppt-Q 810

• Non-destructive testing is the common use of shearography. The defects become visible on measuring their inhomogeneous deformation gradients. Depending on the spatial distribution of deformation the defect or the structure itself can be characterised. The rotor measurements show a dis-bond (left), a crack (right) and a structural transition (centre). Compare fringe density and distribution.

Impact defect detection in carbon fibre composites (CFRP) by dynamic excitation • The examples shows carbon fibre panel with impacts prepared by Airbus, Bremen. Similar carbon composites are used for the new Airbus A 380. Slide 12 | Kim Hallqvist | Q-800 September 2009 Super quality services| sqs ppt-Q 810

Shearography - Capabilities Conclusions Benefits: Contact less Global method, Good sensitivity, Real time inspection, Quicker than most of the NDI methods, Working on all type of materials and structures, Numerical acquisition give rise to efficient follow up, New type of damage are now detectable without opening the structure… The keys of the efficiency are in the selection of the loading and the implementation Slide 17 | Kim Hallqvist | Q-800 September 2009 Super quality services| sqs ppt-Q 810
