DEVELOPMENT OF ADVANCED NON CONTACT METHODS FOR NON DESTRUCTIVE DETECTION OF DEFECTS AND DAMAGE IN AERONAUTICAL STRUCTURES

Objective

The aim of this project is to provide more advanced non destructive inspection techniques.
Many laser ultrasound generation, tests were performed on composite and aluminium samples, studying in particular the dependence of the generated signal on the characteristics of the piezoelectric detector and the signal to noise ratio. With reference to laser ultrasound detection, tests were performed by means of time delay, heterodyne and Confocal Fabry Perot interferometers.

The research into eddy current has involved the development of advanced probes for the inspection of composite structures and the development of a multifrequency data acquisition system.

For shearography, holography, speckle camera and thermography, the result has been the improvement of loading devices, acquisition systems and analysis software as well as the set up of inspection procedures.
To accomplish this the following tasks have to be achieved :
- development of non-contract inspection methods
- evaluation of existing methods currently used in laboratory environment
- evaluation and comparison of different techniques.
