| Résumé : |
This study presents an approach for monitoring the structural health of CFRP using conductive paths of printed silver nanoparticule ink. Both delaminations and surface cracks can be detected by measuring the elctrical resistance during loading. |
| Note de contenu : |
- Materials and specimen preparation
- Electrical resistance measurements along printed paths for surface crack detection
- Electrical measurements through the material for delamination detection
- FIGURES : 1. (a) Specimen geometry, design of conductive paths for measuring resistance along printed paths. (b) Three-point bending test setup with electrical resistance measurement along printed paths - 2. Force and resistance change of conductive paths versus displacement - 3. Light microscopy observation of printed paths after testing - 4. (a) Specimen geometry, design of conductive paths for measuring resistnace through the material. (b) Three-point beinding test setup with four-channel electrical resistance measurement through the material - 5. Force and resistance change of the four measured channels versus displacement - 6. Light microscopy observation of polished sections after testing. Region above electrode 2 and 3 (middle electrodes), inter-libre failures and delaminations and region above electrodes 1 and 4 (outer electrodes), only inter-fibre failures |
