Delamination

Bondline Delamination

A visually clear bondline-separation image that works well for member teaching because the delaminated region is easy to identify and explain.

Observed feature Visible delaminated region along the bondline
Likely mechanism Bondline delamination associated with incomplete adhesive fill

Interpretation

Why this image matters

The report concluded that the delaminations may be the result of lack of adhesive fill at the bondline, with several processing and surface-condition variables still requiring consideration.

That makes this a strong delamination image because the separation is easy to see without needing heavy microstructural explanation.

It is especially useful for teaching that visible interface separation can be real evidence of reduced bond integrity even when the root process issue sits upstream in adhesive coverage or surface preparation.

Best comparison value

  • Teaching bondline delamination with minimal interpretation overhead
  • Discussing incomplete adhesive coverage as an enabling condition
  • Comparing visible separation to more subtle interface problems
