3-D Characterization Of Defects In Epoxy-Matrix Composites

The Situation


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


The Solution



  • 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.
