Bond TestingUltrasonic bond-testing is a useful means of verifying that glued layers of a material are structurally and adhesively bonded together and fit for purpose.

Resonance testing is an effective method for verifying the structure of thin layers of metal or laminate that are bonded together.

A second variation, mechanical impedance analysis (MIA) helps us to detect defects between the skin and core-cells of sandwich structures.

Lastly, pitch-catch technique is particularly useful for detecting skin to core disbands in honeycomb structures.


Most aircraft structures consist of thin layers of aluminium bonded together. Bond testing can be a quick, inexpensive and highly accurate method of finding disbonded areas in aircraft structures (both at manufacturing stage and once in-service).

Helicopter blades, skin panels and many other aircraft contain sandwich structures made from aluminium, fiberglass, or carbon/graphite over a honeycomb core. Bond testing is a highly portable and cost-effective means of verifying structural integrity and ensuring the aircraft is ready for flight.

All our inspectors are level II or level III certified to EN4179 / NAS410.
