Abstract

Foam bonded on metal is a common design in space applications. Despite the fact that high efficacy bonding processes exist, there is no a priori insurance in the bonding quality. So, careful bonding inspection is needed as adhesion loss can be critical during chronology. for small structures there is no real problem, as good NDT methods are available. But, at large scale, not only the quality of the control but also the productivity of the tesing process must be relevant. Such constraints have been taken into account, at Onera, in developing a tool which can be used in industrial environment. Techniques used are not very original and their association has been broadly developed and used in the past. But, the need arose for such a method in inidustrial environments with qualities like fast response, full-field and robust interpretation. This paper describes the ways used to cope with these constraints in designing a tool which seems to be compatible with the targeted application.
