| Résumé : |
Wherever materials properties can contribute to weight savings, it is especially important to optimize the parts. A recent study by the Audi AG and Ottronic Regeltechnik GmbH shows which role non-destructive testing using active thermography can play. |
| Note de contenu : |
- Quality plays a special role
- In-Depth information
- The measuring principle in active thermography
- Testing FCPs with thermoplastic matrices
- Industrial use of the testing system
- Automated testing for mass production
- Even more weight savings
- FIGURES : 1. CFRP in mass production : The space frame of an Audi A8 is the result of multi-material construction - 2. The principle of active thermography : An excitation source heats the test object for a short time, inducing a change in temperature. The temperature signal detected by an infrared detector is processed, evaluated, and displayed graphically - 3. Simulation : Temporal temperature curve (color shading) through the depth of test object for a single heat pulse and the input of several pulses, such as used in the lock-in process. The dotted white line indicates the delay in temperature spreadin - 4. Ottronic ATIIS Vari : Industrially applicable system for active thermography |
