Abstract

The improvement of the UT inspections performances, and especially the defects characterization, needs first of all the design and the use of transducers with high electrical and acoustical characteristics. The technology of the 1-3 composites materials recently brought in the field of non-destructive testing applications, allows to make decisive progress in the improvement of the above parameters. The exceptionnal piezo-electrical properties of the composite materials, their shaping capacity, their thermal properties and other very good features of these materials already under control, allow the manufacturing of a new generation of transducers, by being released of many restrictions of the conventional technologies : ceramics or piezo-electrical polymers. 3 examples of applications in the nuclear field show all the benefits of this technology and allow to forecast a large diffusion in the near future.
