3-D Characterization Of Defects In Epoxy-Matrix Composites
Client wanted a technique to detect and quantify fiber defects such as wrinkling and waviness in continuous glass fiber reinforced epoxy matrix composites used in helicopter blades
- Use Microfocus Computed Tomography with special beam hardening to detect low-contrast fibers with high fidelity.
- Perform 3-D reconstruction to understand fiber defects in all orientations and generate critical orientation serial sections through the volume.
- Perform physical serial sectioning and compare the sections to CT data to establish one-to-one correspondence for technique validation and POD estimation.
