Method and device for controlling non-destructive holographic interferometry of enclosures in the composite material reel on metallic liner.

摘要

- the invention relates to a method and device for the non-destructive testing by interferometry holographic of containers made of composite material which is wound on a metal liner. & br / - the process of the invention is a control method in which it is made to interfere with two holographic images of the same zone to be controlled, taken in two different states of stress, characterized in that the second image is taken after having brought the liner of the enclosure (1) at a temperature different from that it had at the moment of the first image. & br / - application in particular to the tanks for storing gas under high pressure.
