| Résumé : |
The local fiber orientation in composite materials can be analyzed non-destructively using microcomputed ‧tomography. In practice, however, usually small samples are taken from larger components in order to avoid imaging errors. However, the ROI method allows parts of a size relevant to practice to be analyzed directly. |

- FRP part from a car engine compartment
- Local fiber-orientation analysis
- Comparison with flow simulation
- Figure : The (halved) front carrier from an auto engine compartment used for elucidating the measurement method, with four region of interest marked with crosses.
- Fig. 1 : Volume rendering of the region marked green in the Title figure and cross-sections from the 3D images of region of interest A3 with highest and lowest resolution
- Fig. 2 : Diagonal components of the 2nd order orientation tensor measured from the CT images. Sections through the 3D images in the xz-direction in the coordinate system from Figure 2 are shown (y : injection direction, z: thickness direction)
- Fig. 3 : Diagonal components of the 2nd order orientation tensor, comparison of the orientation predicted by injection molding simulation (orange) and the orientation measured in the 3D images with highest resolution (green).The position of the regions used in the simulation is marked red in the volume rendering
- Table 1 : Diagonal components of the 2nd order orientation tensor, measured in 3D images of the region of interest with different resolutions |
