"Pressure hulls should be made out of contiguous material like steel, titanium, ceramic or acrylic, he explained, in order to do modeling and finite element analysis to "understand the number of cycles that it can take." That's not the case with a composite material, like carbon fiber, made of two different materials blended together.
"And so we all knew that the danger was delamination and progressive failure over time with microscopic water ingress and ... what they call cycling fatigue," he added. "And we knew if the sub passed its pressure test it wasn't gonna fail on its first dive ... but it's going to fail over time, which is insidious. You don't get that with steel or titanium."

The shape was weak. High pressure hulls are spherical or cylindrical with spherical ends like a propane tank. Any other shape is weak.
A first year engineering student knows this.
They did not do fatigue testing with their novel material for this extreme application.
Just like they didn’t test the clot shot for short or long term, for the “novel virus”.
Their playbook is old, tired, and EVIL.
However, look the other way...
That is the same carbon crap they are making washing machines out of! To hold water...instead of real metal. China junk.
Now...that is a washing machine. I can't imagine going down there in one of those! Don't care how thick.
