The replacement of metals by composite materials aims to lighten parts while natively endowing them with new functionalities. The manufacturing quality of composite parts can be validated with certain non-destructive testing techniques traditionally used for the inspection of welds and other metal components. However, these techniques must be adapted to the particularities of composites and the specificity of the defects sought. On composite parts, it is often difficult to distinguish the defects strictly speaking from the differences in the structures of the material. Two techniques are particularly suitable for the detection of these defects: ultrasonic non-destructive testing and infrared thermography.

Our 8 questions
1 – Are traditional non-destructive testing techniques suitable for the inspection of composite parts?
2 – What are the particularities of the defects sought on composite materials?
3 – What are the main elements to consider when choosing the most suitable method for an industrial need for non-destructive testing of composite parts?
4 – What are the difficulties and specificities of the implementation of NDT on composite parts?
5 – Have new techniques been developed specifically for the control of composites?
6 – Can certain techniques be used both in production and in the laboratory?
7 – Does the implementation of NDT for composite inspection require specific skills?
8 – On what aspects do non-destructive testing still need to evolve to best meet the inspection requirements for composite materials?
