NON DESTRUCTIVE CONTROL DEVICE AND PROCESS USING HOLOGRAPHIC INTERFEROMETRY ON ENCLOSURES MADE OF COMPOSITE MATERIAL WINDED ON A METAL LINER

摘要

the invention relates to a process for the non-destructive testing of holographic interferometry for composite coiled bodies in the metallic liner interfering imagesthe area was made in two states to control thermal stress are different.characterized in that the thermal stress is applied uniformly to the whole of the liner.the interior of the enclosure, and the taking of interfu00e9rogramme is carried out to the outside of the enclosure.in this, the second image is taken after the liner (2) at a temperature different from that at the time of the first image and the initiation of thethe second image is taken of the order to the detection on the outside and in the vicinity of the enclosure (1), a variation due to the change of temperature caused by the liner (2).the infrared radiation emitted from the body outside of a predetermined threshold. application in particular to tanks for the storage of gas under high pressure. figure 3.
