METHOD OF IDENTIFYING AND/OR TRACKING DEFORMATION OF A TURBINE ENGINE PART

摘要

The invention relates to a method of identifying and/or tracking deformation of a mechanical part (14) made of composite material for a turbine engine, the part comprising a preform (26) of fiber material and a resin (24). The method consists in incorporating metal particles (22) in the preform or the resin (24) during fabrication of the part (14), and in subjecting the mechanical part (14) to two X-ray inspections on two different occasions so as to identify the part (14) and/or so as to deduce deformation of its internal structure.

1. A method of identifying and/or tracking deformation in a mechanical part (14) made of composite material for a turbine engine, the part comprising a preform (26) of fiber material together with resin (24), the method being characterized in that it consists in:
incorporating metal particles (22) in the preform and/or the resin (24) while fabricating the part (14); subjecting the mechanical part (14) to a first X-ray inspection so as to obtain first information about the positions of particles within the part; then subjecting the mechanical part (14) to a second X-ray inspection on a later occasion so as to obtain second information about the positions of particles within the part; and identifying the part (14) and/or deducing the deformation of its internal structure by comparing the first information about the positions of particles within the part as obtained respectively with the first X-ray inspection and the second information as obtained with the second X-ray inspection.
