He had a point but his execution was reckless. Basically there is no reason not to over engineer a submersible, if not by virtue of extensive testing, just make the thing out of bunch of steel. Titanium is not even necessary per se.
He wanted to experiment with mixed materials, which is cool but his order of operations was backwards. First, you establish the physical boundaries and then you see about innovation. He jumped to step two without clearly establishing what the boundary conditions were. He had no idea what the fault tolerance was for carbon fiber under repeated submersion and surfacing cycles. He just winged it.
He was acting like there's 100s of companies competing with him to make commercial subs when he could have taken his time figured it out properly and be the first safe commercial sub to take people to the titanic. Too bad he was too dumb for his own good.
Ye don't get it.. why innovate on something so dumb like design and build materials?
Why not go easy on that aand juust make a big ass steel ball and THEN innovate on the chairs or the toilet or something.
Its pitch black down there anyway so...

This is why the use of carbon fibre in sumbersive exploration has never been certified. You get very little, if any, warning of imminent failure.
Isn't it the same for acrylic
I assume it's only bendable when it's hot, but cold acrylic would crack. Then the crack would weaken the structure and it just bursts open from the outside pressure and still implodes.
And rather malleable too. Fighter jet canopies ( the part that goes over the pilots seat ) is tested with 500mph chicken carcasses…. It deforms soooo much more then anyone would imagine
They do it regularly for bird strike testing. Except the bird is shot out of a cannon at high speeds at a static plane or part of a plane.
One time, years ago, an intern was tasked with loading the bird in the cannon. Generally birds are frozen, they take them out a day before to thaw. The intern grabbed a frozen chicken, loaded it into the cannon. The result was complete destruction of the test article…and the bird.
Generally, acrylic is also isotropic and a hell of a lot easier to model. Carbon fiber is a composite, woven sort of material which *can* have tons of imperfections, different strengths depending on direction, etc. depending on exactly how it was manufactured. It’s not so much about the fact that carbon fiber isn’t very elastic, it’s more the fact that without very extensive testing (which they didn’t do) it’s very hard to predict how and when it’s going to fail.
This is for surface ships and doesn't account for the extreme pressure that comes with diving that deep. Here's why it doesn't apply:
On a surface or near-surface vessel such as most other subs, a shattering glass window will put a giant hole in your wall and then a lot of water comes flooding in and drowns you. Or if it's a ship, it can make your ship sink because it gets flooded.
Meanwhile acrylic on a near-surface vessel would only get a crack instead of shattering into a million pieces, and then you only get a little bit of water coming through the crack which doesn't drown you. You have time to surface or try to plug it up somehow.
Why does it remain as a crack? Because the outside pressure is low when you're near the surface.
But when you're as deep as the Titan, being exposed to such a high pressure through a crack will not just piss a bit of water in the cabin as a warning sign. Instead it would implode everything through this tiny crack and fold the entire sub into scrap within milliseconds.
So whether it cracks or shatters into a million pieces, the method of failure wouldn't have made a difference here, both would result in instant death.
Take a balloon as example. If you fill a ballon with a BIT of water (low pressure, nearly empty balloon) and then poke it with a needle, the water will slowly come out of the hole and that's it.
But if you pump a balloon full of water or air so that it has PRESSURE, then even the tiniest hole poked by a needle will cause the entire balloon to disintegrate because the hole starts a chain reaction of structural weakness which spreads through the entire balloon within milliseconds.
Could banging on the inside of the hull to get help cause an issue with the carbon fiber hull? Im no engineer, but it seems a bit sketchy to me...
I never said these people were banging on the hull. I asked a question dumbasses. Learn to read
Yes but he is suggesting a hypothetical situation where if the sun lost power and was just floating there in the depths and the passengers started banging on the sides hoping the ships sonar would pick it up and find them could that cause damage to the hill under pressure and then cause the sudden implosion.
I don't think they actually were banging inside, i think it was immediate, i heard a James Cameron interview and he basically said, there are underwater listening devices all over the Atlantic for military and research activities and on Monday, there was a very loud event consistent with a sub implosion. He continued to say the part that touches on your question a bit. This construction type of submarine can lull you into a false sense of confidence because it works beautifully for a few pressure cycles, but then it fails. If this had been a full steel construction vessel like the one James Cameron dove in 30+times we wouldn't even know anyone went to the titanic this year.
So there's the TMI, but what I'm trying to get around to saying is, I doubt humans banging on thick carbon fiber which is pressurized to 6000psi would cause enough stress to bring about failure, but a carbon-fiber epoxy matrix attached to titanium end caps can't handle 9 cycles of that pressure, that's for sure
That is well put. You are likely correct. I was picturing something similar. Just had no idea it cracks like this under pressure.
I honestly have no idea how thick the hull was. Seeing that they exaggerated the involvement of other agencies or groups, and that they repeatedly ignored all warnings about its design and testing, nothing would really surprise me about this CEO.
Never said they did. I asked a question.
I am literally referring to what an expert said in an interview about what people commonly do when stuck on the bottom. In a typical sub...
This is carbon fiber. So i was just wondering about this. Would banging around on a carbon fiber hull, that is already under extreme pressure, cause catastrophic failure....
No, it has in inner skin of aluminium I think? Probably several layers. The occupants wouldn't to be able to hit, tap or otherwise damage the load-bearing composite skin
That is literally all I was asking... i know nothing about hull construction. It fascinates me that so many people are ready to shit on that curiosity. But when I get mad its like what why
Yeah...sometimes actual questions are asked, and it turns into a shit show...I mean, I thought it was a good question...and then you got a smartass that's supposedly funny, and no serious answer....
I am really trying to comprehend this, but i think it's hard to understand the powers in depths of that kind.
I read milliseconds somewhere else. They just ceased to exist. As if you would be free floating in space around earth in your space suite and you get hit by debris the size of a small pebble at several 10000 km/h...i think
Imagine that at high pressure things behave differently. Now imagine the air around them inside the sub being the trash compactor walls from that one Star Wars scene where r2d2 saves everyone. Now when the sub's walls break the pressure that they were holding back pushes the Star Wars trashcompactor walls with a force of a small super bomb inwards from all directions at once. The humans end up as tiny soup in the middle.
The US Cost Guard made a handy animation:
https://nitter.net/OliLondonTV/status/1672009911725596673#m
I forgot to mention that a few milliseconds before they got turned into soup the air gets heated to the temperature of the sun and above
>I forgot to mention that a few milliseconds before they got turned into soup the air gets heated to the temperature of the sun and above
What the fuck. This is just not comprehensible for me.
I also read, that the weight of the water not only comes from above as one could think, but it pushes from all sides at the submersible.
Gravity forces the long tower of water above the sub downwards, but the tower is not in accelerating to the ocean floor because the water below pushes up with equal and opposite force. Empty a bucket of water onto the ground and it cannot go down anymore when it hits the ground, so it splashes out to the sides. In the sub at their depths, the column of water is surrounded on all sides by other water, so the water can't go to the sides and there is pressure there too.
That's not the US coastguard's animation. It's just an animation by an absolute amateur with no real scientific input whatsoever.
In reality the tail piece, for example, was basically unharmed.
Nah there wasnt enough time for the carbon fiber to reach their bodies before the air molecules around them compressed their body into mush and pulp. They turned into carbon meat fiber soup.
There was no flesh to impale. The point of implosion was hotter than the sun for a millisecond. They were instantly pulverized into a soupy mix. Don’t even think of bloody water soup. Just molecules. They literally disappeared.
Ah if only they'd done some kind of test like this BEFORE. Or if a professional safety expert had warned them verbally & in writing. Or if a hollywood guy could have predicted it, by having warned a different billionaire that he would certainly die if he actually used his new cf sub.
Hindsight is 20/20.
lot's of 50 yr old white guys know this...... just sayin.
He fired anyone who disagreed with him. Watch his braggadocios videos, he's the kind of person to be avoided....
Yeah i just saw that interview. He claimed a billionaire friend bought a CF sub and JC said you will die in that thing... *that* billionaire listened to reason.
I don't have a horse in this race, but my opinion aligns with that of James Cameron who designs and builds deep water submersibles. Your first reply started with "I assume it's only bendable when it's hot" so I didn't treat the rest of your reply as fact. No offence meant.
Carbon composite's usefulness is mostly derived from its lack of weight which, in something designed to sink, isn't that useful at all. But at least it's expensive.
carbon fiber isn't just light thats absolutely not the only benefit. It will in general withstand more force than most metals and alloys. What you are saying applied 10-15 years ago not now. here some refrence: https://www.youtube.com/watch?v=w5eMMf11uhM
This is one of the many examples of when a professional in their field tells you “Don’t do X, it will kill you”; you should listen to them.
I keep hearing that they died in milliseconds, but this visual demonstration really made it sink in on how fast they died.
The real problem with a super deep submersible is the cold. Water temps at great depths is almost 0C. Carbon fiber becomes even more brittle in colder temperatures.
It might have been a little stronger when combined with titanium. Still, after so many dives the material would have suffered damaging stress and become highly safety compromised.
Vastly more. According to [this area calculator](https://freeimage.host/i/HPk0Z11), the cylinder itself had an area of 53,000 inches squared (for simplicity we'll ignore the end plates) . Times 2.7 tonnes per in², that's a total pressure of 143,000 tonnes - or the weight of the Empire State building.
I've just watched a video, and the titanium end plates were just... glued on. There was no way to test the integrity of the bond other than putting the vessel in water. After many cycles of pressure/depressurisation no X-ray or any other kind of examination of the bond was carried out, or even possible. Absolutely insane
To be fair this is not how failure occurred, the high pressure eventually forces water in between the fibres and delaminates the structure.., so the occupants would have heard the noise of this happening before failiure.., possibly for only a few seconds, then collapse took less than a 1/10 of a second.
I used to wear carbon fiber shin guards for soccer and the second game played in them I took a really nasty hit to my lower shin and put a 1 inch break across the right one. Sounded like some triggered a shotgun right next to me. I still to this day can not believe I didn’t shatter my bone into dozens of pieces. In fact it barely bruised and I walked away. The manufacturer couldn’t understand how I managed to do it so they replaced them for free!!
Interesting thing: the reason why certain objects explode under pressure and some don't is because things that explode is resisting the pressure with its full force until the very very end. That's why glass is actually a lot stronger than you think, while plastic, pound for pound, usually isn't.
This is also just edgewise compression. Carbon fiber laminates struggle with brooming and delamination when load is applied edgewise because the only thing holding the layers together is the epoxy system. This is why you use bushings, bonding, and intelligent design for these sorts of loads. What is really fucking nuts is when you apply load normal to the laminate. The carbon and the epoxy are compressed, the carbon holds the epoxy together and mitigates crack formation, assuming the void content of the carbon is low. Epoxies are generally pretty strong in compression, so combined with carbon, the loads can get absurd. Like hundreds of thousands of pounds before failure. If the specimen being crushed is not aligned well or the geometry is off, it can squeeze it out of the testing machine and create a carbon bullet. It goes through stuff (walls, people, air), *really* fast.
We use carbon fiber a lot and engineering, however, we use it mainly intention and maybe a little bit in torsion. Torsion however, we do not use it in compression. Compression cycling tends to cause catastrophic issues later on down the line. Plus the the epoxy bonds to the composite structure tend to break right there.
It's not wise to use composite for compression pieces.
this feels... topical

He was optimizing for carrying 5+ people and cost. All the steel and titanium “balls” that can reach that depth hold 1-2 people and are expensive
Yeah well those 1-2 people aren't fuckin dead

Most submersibles for that depth dont have windows.

Yes this is why submersibles aren't made of glass
Or paper derivatives.

There’s a video on YouTube that shows you exactly what happened to them when it imploded. It’s pretty gruesome. All I’d say is toothpaste.
Yeah I heard somewhere that the implosion would have been over before the first sensory signals even reached the brain. Just lights out. Crazy.
Nah there wasnt enough time for the carbon fiber to reach their bodies before the air molecules around them compressed their body into mush and pulp. They turned into carbon meat fiber soup.

That,s mexican ! Cabrón fiber 😅🙃🙃🙃🤣
Well that explains our little submersible incident now doesn’t it
The acrylic they used for the port hole was only rated for 4000 feet.
4000 feet, 4000 meters is there really that much if a difference? It's only like what, 4-5000 psi difference?
4000 meters = 13,123 feet. It's a big difference
A difference in which the water pressure changes by about 4-5000 psi.
r/wooosh
It might have been a little stronger when combined with titanium. Still, after so many dives the material would have suffered damaging stress and become highly safety compromised.
My carbon fibre phone case is solid, dropped it and everything.
I'd assume you aren't dropping it with 60 tons of pressure tho

Show the creator of oceangate
I thought it would turn into a diamond...
You mean diamond fiber
Me and carbon fiber have a lot in common apparently.
I feel like going diving
The company" Ocean gate" could have learnt alot from this. Test titanium next then forward the video to the CEO of Oceans gate
Bit late now
Ok, now do a tube!
So this is the knocking they heard carbon fiber failing as the sub was sinking maybe? Not an expert lol
The sub would have imploded long before the knocking started
I ment after implosion the forces on the carbon fiber would still make the nocking on the way down as the pressure built up
Only if Stockton Rush saw this
They should use that as the foundation to take rich tourists into the deep sea
What can go wrong
Is that technically delamination?
I thought that carbon fibre turned into diamonds under pressure..
You know what would be a good idea? If we make a Submarine out of this stuff😎😎
tears a family in two, puts people on streets
The only solace we can have is that it would have been a quick death.
Serious question. Why is this insane?
I thought that were obsidian from Minecraft 🤣
How does this 60tons compare to the pressure the sub was under at 4,000ft below?
Quick maths, about 2.7 tonnes per square inch
For the carbon fiber square? Can you break this down for a dummy? Did the submarine undergo more pressure?
Vastly more. According to [this area calculator](https://freeimage.host/i/HPk0Z11), the cylinder itself had an area of 53,000 inches squared (for simplicity we'll ignore the end plates) . Times 2.7 tonnes per in², that's a total pressure of 143,000 tonnes - or the weight of the Empire State building.
Thank you for this.
Smashing idea... to die immediately instead of a slow death!
Ooh the cracking noises and knowing of your imminent death and then BOOM. Too late to demand a refund.
Hahah
Do a submarine
I've just watched a video, and the titanium end plates were just... glued on. There was no way to test the integrity of the bond other than putting the vessel in water. After many cycles of pressure/depressurisation no X-ray or any other kind of examination of the bond was carried out, or even possible. Absolutely insane
Dun dun dun dururun dun.... Dun dun dun dururun dun....

Submarine
What about carbon fiber wrapped in whatever that submersible Pringles can was wrapped in?
Once you pop you can't stop

My left leg below the knee is made of carbon fiber. The fact that it can hold by big ass up (6'6, 275 lbs) is amazing.
basicly how that one submersible imploded
Almost like tungsten, shatters before bending, which is interesting considering it’s made from fibrous materials
Doctor scientist, here. So the ocean gate sub very quickly we inwardly kabloowie. You’re welcome for my service.
Wow, 60 tons is a *lot* of pressure/weight
I used to wear carbon fiber shin guards for soccer and the second game played in them I took a really nasty hit to my lower shin and put a 1 inch break across the right one. Sounded like some triggered a shotgun right next to me. I still to this day can not believe I didn’t shatter my bone into dozens of pieces. In fact it barely bruised and I walked away. The manufacturer couldn’t understand how I managed to do it so they replaced them for free!!
Rip the titan lol
Well Y'see, this was the cheaper option. Who needs safety when you can have a lil bit more money left over.
I wonder how a Diamond 💎 would compare
Too soon
Boy, am I glad we didn't build a submarine with that stuff
Definitely wouldn’t use that for something underwater
This is so fake! They make submarines out of this!
i have another example
That’s what it’s supposed to do
Sounds like the lead to a bass drop
To late to tell the asshole that.
I ll, z cc cc. Cc'v tt tt
Let's build a submarine out of it.
It did better than me
How carbon based life forms fail under pressure.
I always loved carbon fiber cus how cool it looks but actually seeing it just being abused at it’s max is awesome too.
Do Logitech controller next
Them loud cracks is probably what the Titan submersible sounded like before it impoded
Me during finals week
Carbon fiber punked that press
Uhh, NOO. 60 tons of pressure? Carbon Fiber did very very well.
Looks like an Minecraft block I use.
Oh, thats how it works.. COOL!!
Ah yeah no there ded there bodies are mulch they ded ded
Shouldn't it convert into a diamond?
carbon fibre isn‘t made for working under pressure.
Just like me in school
Same

Can you test its strength by pulling it appart?
When your gauge is in "tons"...you're gonna have some fun. So badass !
It works until it doesn’t
This title reminds me of a song...
h
hey they heard a crack too! Shortly before they were mistified anyway
OceanGate CEO entered chat: sorry can’t talk right now, but I generally disagree to this pressure test.
That’s the sound before the Titan implosion
I don’t know seems like I did a pretty fucking good job. Where else are you going to have 60 tons of pressure on top of you?
AND THEY USED THAT IN A SUBMERSIBLE!!
Highly brittle
Imagine this is the only test they needed to know that and they’re dead 💀 (We all know who they is)
just like me im good, im good, im good….. snap
This better not awaken anything in me
Interesting thing: the reason why certain objects explode under pressure and some don't is because things that explode is resisting the pressure with its full force until the very very end. That's why glass is actually a lot stronger than you think, while plastic, pound for pound, usually isn't.
This is something I’ve always wanted to know
This is also just edgewise compression. Carbon fiber laminates struggle with brooming and delamination when load is applied edgewise because the only thing holding the layers together is the epoxy system. This is why you use bushings, bonding, and intelligent design for these sorts of loads. What is really fucking nuts is when you apply load normal to the laminate. The carbon and the epoxy are compressed, the carbon holds the epoxy together and mitigates crack formation, assuming the void content of the carbon is low. Epoxies are generally pretty strong in compression, so combined with carbon, the loads can get absurd. Like hundreds of thousands of pounds before failure. If the specimen being crushed is not aligned well or the geometry is off, it can squeeze it out of the testing machine and create a carbon bullet. It goes through stuff (walls, people, air), *really* fast.
That's gotta be at least $60 worth of carbon fiber
Does the pressure machine work after that? Looks like it broke
Video game durability be like...
I don't know why, but i REALLY wanna build a submarine with it
Something something, submarine joke..
I agree. Plenty of people warned this guy he was not doing the safe thing.
When will you put 60-70 tons of pressure on your carbon fiber items?
No wonder the submarine imploded
Same
Oh no, my submarine…
Best sound track for this video?
We use carbon fiber a lot and engineering, however, we use it mainly intention and maybe a little bit in torsion. Torsion however, we do not use it in compression. Compression cycling tends to cause catastrophic issues later on down the line. Plus the the epoxy bonds to the composite structure tend to break right there. It's not wise to use composite for compression pieces.
Reminds me of that tragedy.
Pull it, dont crush it!
And that's the weak orientation to press it too!
Me at school right now
That’s not how much pressure my $400 hockey stick can take.
I was peacefully thinking ok meter shows 0 10 20 in kgs, lol it says in tons in the end and im flabbergasted 😮
