The 'weaving' is supposed to be link connecting your two hands together interlocking fingers, in one direction you will meet a full resistance, but in the opposite direction your fingers will unlock.
I have no idea but seems to me if there is external pressure the weaving would have 'imploded' depending on the design I guess. Really want to know more about this.
Tensile load capacity is pretty much the resin that keeps the fibers from moving.
The most I could find about the design
> The entire pressure vessel is comprised of two titanium hemispheres, two matching titanium interface rings, and the 142 cm (56") internal diameter, 2.4-m (100") long carbon fiber wound cylinder – the largest such device ever built for use in a manned submersible.
suggest that yeah, they relied entirely on its compressive strength of it
I'd like to say it's caveat being as you mentioned but honestly, given then community in this field, even the technical diving alone. Someone must have said it to them.
Thanks for some numbers, maybe tomorrow will play with the simulations to determine the AP's that could collapse the craft. The titanium hemispheres are probably the best option but the sealing would need to be almost clinical.
I'm anxious just thinking about the construction of this sub.

I guess it's in the spirit of the Titanic to kill your passengers doing dumb stuff.
Buckling is not a material failure, it's a structural failure. In pure buckling [0], the strength of the material is not actually a factor in whether something buckles or not. In most cases, material failure does occur as a side effect of the buckling, but not always. (The material's stiffness does matter, though. All else equal, something that's more flexible will buckle sooner than something stiff.)
Rope.
I think this might have been the first one. In minimal fairness, at least the owner put his money where is mouth was.
Sidebar : The owner/ceo did a 10 hour overall at max ~3kMeteres
A lot of measure of units thrown around in this thread too.

There’s also a documentary on bbc about one of those trips
I took that to mean this was their 5th trip with this submersible
But that’s the thing about ratings. The manufacturer guarantees safe usage at 15 PSI and anything above that all bets are off and you’re on your own. Same with milk and expiration dates. Many times the milk is fine after the date, but the dairy won’t guarantee freshness and food safety.
Same for this looking glass. It says what the CEO thought about safety. He was willing to take chances and roll the dice. And every once in a while you get snake eyes. The consequences of rolling • • at 9,000ft of depth in the ocean is sadly instant soup. The water entering the vessel would likely be 5,000F degrees or so. While some people say it would be an instant death and not consciously detectable, I disagree. I think they were given just enough time for the brain to go oh shit, but only got to the oh part, and lights out.
Looking glass rated 4k 'feet' around 1200 meters..
Not sure as there is a video of the ceo going to 3k meters solo in the titan on a 10~ hour trip..
That said, not much of this craft was 'rated' for anything..
https://navalpost.com/how-deep-can-a-submarine-dive/ The depth limits of the most known nuclear powered submarines’ depth limits, as follows;
Typhoon-class: Test depth 900 m (3,000 ft) Astute-class: Over 300 m (984 ft 3 in) Akula-class: 480 m (1,570 ft) test depth for Akula I and Akula I Improved, 520 m (1,710 ft) for Akula II and III, 600 m (2,000 ft) maximum operating depth Ohio-class: Test depth >240 m (800+ ft) Virginia-class: Test depth >240 m (800+ ft) Borei-class: Test depth 950 m Rubis-class: Test depth 350 m Barracuda-class: Test depth >350 m
We really don’t know what depth the noise was comming from.
That being said it is vanishingly unlikely that an unrelated submarine trying to remain stealthy would be banging on their hull every half an hour.
The Titanic is at 3800 meters. That it's reachable, by private organizations no less, is just a marvel.
That's also why military specs on things like this are always lies, you don't want anyone knowing how deep you can actually go, which likely includes most of the crew.
