Carbon fiber is a great material for certain things like skis and bike frames. A submersible vehicle just isn't one application where carbon fiber is useful. The reason is the material micro fractures under stress. Sure, it's extremely strong. It's also very brittle. Every time it's put under extreme pressure, it flexes and creates new micro fractures. For skis and bike frames, this only becomes a problem after many years of use. Then the integrity starts to fail gradually.

In the case of the submersible, the failure will suddenly occur with no warning.

It just reinforces the CEO's utter disdain for safety and his neurotic fetish for taking the cheaper options - with everything in the build - hell he couldnt be assed doing the CF in a sealed controlled environment and vent it to prevent contamination and bubbling in the layers etc asd others have previously mentioned. His 'new for purpose' acoustic detection apparatus was a complete joke , its just peachy to know your hull is stressed and at catastrophic failure and now you have a 2 hr ascent to manage. Lmao -fcking tards - all of them

It was all to save a few bucks here and there. He literally jewed himself to death.

No way were they going to control the ascent. Their plan was to shed weight.

Oh yeah totally, i meant in that - if the ascent is 2 hrs back to the surface from 13000ft, and even if his fancy pants acoustic dinger chimed beforehand - that is a long time to hope and pray you reach the top with a 'critical infrastructure collapse impending'. Not sure how much that ascent process is sped up with all possible weight shed tho .
