Composites Failure Analysis — narrowing down root-cause candidates from defect location and process history.
Case image: crack at a dissimilar-resin lamination zone
We examine cure shrinkage and thermal expansion mismatch, interfacial adhesion, cure history and residual stress as root-cause candidates. A specific cause is not confirmed from a photo alone.
Typical Requests
- Cracks, delamination, dry spots and voids
- Strength variation, uneven impregnation and dimensional deviation
Review Method
- Comparing defect location with process history
- Linked review of cross-section, composition, thermal properties and mechanical properties
When publishing an actual case, we confirm the customer’s consent to disclosure and the supporting test evidence.
