Key characteristics
The mission of CEA Tech Pays de la Loire is to develop and disseminate technologies to benefit the industry by ensuring a “bridge” between the scientific world and the economic world. It provides access to the key generic technologies developed by the other CEA operational divisions.
Robotized computed tomography key characteristics:
- Scanning capabilities for large work pieces (up to 7 m)
- High resolution non destructive testing for the evaluation of advanced material internal structure
- Multi-resolution and multi-energy image processing
Equipment
- Large scale shielded housing (9 m x 6 m x 4 m)
- Cooperative robots moving with high precision and high repeatability
- 225 kV micro-focus X-ray generator
- Different detectors : high scale (400 x 400 mm), high resolution (50 µm pixel size), multi-spectral (material discrimination)
- Image processing and 3D reconstruction algorithms
- Simulation software for control optimization
Services
- 3D non-destructive inspection and testing
- Novel means to image, control and monitor large and/or complex parts
- Acquisition adapted to the studied object (reduction of the times of acquisition, strong swelling on zone of interest)
- Support for further developments of manufacturing technologies and emerging processes (composite, metal, assembly)
- Detection of typical defects like inclusion or porosity, welding defects or delamination, Fatigue or environment tests
Example of MRE applications
- Non-destructive characterization of sections wind turbines blades of significant size for the development of innovating manufacturing processes
- Non-destructive characterization of EMR parts between two cycles of ageing or tests. Analysis of the evolution of the internal defects.
- Inspection of radomes, complex structures
