I have yet to see anyone stop at the absurdity of wrapping the hull of a submarine with carbon fiber. These fibers have high tensile strength. In this case, however, high compressive strength is needed from the outside!
The strongest thread won't do it, that would have to be the pressure inside the submarine and not outside.
It's like pulling a string.
Or an analogy with the implosion of a large cistern, which can withstand the great pressure of its contents, but when the air is sucked out of it, collapses due to the mere atmospheric pressure from the outside.
That actually happened here. The hull, solid under pressure from the inside, collapsed after pressure from the outside.
I don't understand. Who invented it?
When used in aircraft wings, the fibers are stressed by tension, which they can withstand perfectly, not by pressure.
Using them on a submarine is a super stupid idea. Try wrapping a coke can with steel wire. Then try to squeeze it. It will go as easily as if the cable was not there. Another thing would be to pump it from the inside, it would withstand high pressure.
The plastic garden hose is reinforced with strong fibers. Thanks to them, it has great compressive strength from the inside out, but none from the outside, you squeeze it with two fingers!
That's how stupid the Titan submarine is "designed".
