Shearography - New NDT Method
Shearography is a non-destructive measurement method that allows the detection of defects and sub-surface delaminations in composite material. As new NDT method Shearography enables a non-contact inspection and delivers full-field results obtaining 1,4 Million data points per measurement. Therefore Shearography is considered as a very fast complementary method for conventional NDT methods.
In this section we have provided you for download a selection of Shearography applications on various material and components:
Shearography on Composite pressure tanks
Composite pressure tanks are more and more used as an alternative to conventional pressure tanks of steel. Due to its stability and light weight construction there will be a continuing high appeal in the future for the use carbon pressure vessels. To ensure high quality from production to end-user fast NDT solutions are sought.
Shearography on Kissing Bond NDT
Kissing bonds are a challenging task for NDT approach. It is characterized as a bonding with 10% of mechanical properties. Detecting Kissing Bonds pose a high end challenge for manufacturers and NDT staff. Therefore in this framework of testing one artificial Kissing Bond has been introduced into the CFRP foam core demonstrator material in order to provide a first approach of guidelines for detecting this defect type.
Shearography NDT on acoustic liner panel
For composite acoustic liner material as it is used on turbine housing a fast approach for NDT is more and more needed. Therefore this application note describes NDT on an acoustic liner demonstrator panel in order to illustrate the possibilities and advantages that Shearography offer on such structures.
Shearography-NDT on Aluminium Honeycomb Material
Aircraft structures are facing high stress during the usage in their lifetime. Therefore, a constant control and maintenance of those structures is necessary. In this application report possible damages to aircraft structures on aluminium honeycomb panel are simulated. Such as top-layer – core delaminations, back-layer core delaminations and impact damages.
Airbus NDT-Inspection Team uses Steinbichler ISISmobile 3000 Shearography System
Successful cooperation between Airbus and Steinbichler Optotechnik in applying the shearography method for the non-destructive testing of composite materialsSince 2003, Airbus uses a Steinbichler shearography system on various Airbus sites in Germany and France. The NDT inspection team has a ISISmobile 3000 in operation which covers a measurement area of nearly DIN A3 paper size and has proven a reliable tool for Airbus quality assurance. Due to the system´s high resolution (provided by the shearography method - 30 nm out-of-plane), possible defects can be found throughout various material combinations and defect depths.
