I heard pressure testing of the carbon fiber wasn't done. They relied on sensors to detect delamination instead. In software engineering, a component is both created and unit tested with tests on relevant functionality. Delamination sensors are poor compensation for a missing test. They probably didn't test the delamination sensors, either.

As the article mentions though, one of the issues with using carbon fiber for this is that unlike titanium, it weakens with each pressure test.

Also that you can't very effectively model a composite materiál the way you can a solid single material.
