The one-of-a-kind Titan submersible that imploded on its descent to the site of the Titanic this week, killing all five passengers, was made with experimental materials, including carbon fiber, which experts say has not been pressure-tested over time in such extreme depths.
Since the fatal dive, the innovation behind the Titan and OceanGate Expeditions — the company that owned and operated the vessel for paid tours to the Titanic — has come under increased and intense scrutiny.
Days after the Titan was reported missing, sparking a frantic search, the U.S. Coast Guard said Thursday that the 22-foot craft imploded, though officials do not yet know when or why.

Did you also hear that everyone knew exactly what happened and where the wreckage was located immediately after it imploded?
The “90 hours of oxygen” lie and the frantic searching all over the Atlantic was a manufactured charade to keep Hunter Biden out of the news for a week.
What a BS article. Carbon fiber is used all over and IS NOT experimental. Our media are so stupid it is dangerous. They are liars, charlatans, and truly the enemy of the people. I have been working with the stuff over 25 years in the aircraft industry.
From another post...
“According to Weissman, Rush had bought the carbon fiber used to make the Titan “at a big discount from Boeing,” because “it was past its shelf life for use in airplanes.”
Doubt they kept it in temp controlled environment.
The communications mode is typical for undersea communications. It is a sound-based transceiver that delivers digital packets. The carrier frequency is too low to permit the transmission of voice.
It is frustrating reading these stories with an engineering back ground and have been working with CF for years. Regardless of the shelf life expiring it was the wrong material for compressive loads. The CF does not expire, the epoxy binders expire for certified aircraft use.
Carbon with oxygen in the air. CO2.
Looks like Mr. Rush CUT CORNERS!
No, they always tested it with people in it.
I have seen a video of it being wound. Five inches thick just like ribbon onto a bobbin. If the structure was going to hold high pressure inside a cylinder it might have made some sense, but compressive strength — nah.
Thank you... I am one of those engineers that have designed around the stuff for years. Tensile strength of good CF is up to 150kpi. Compression 0 kpsi. I give this example. Try pushing one end of a rope from the other end. If they had hired an uninspiring 50 year old white dude like me, I would have told them hell no. I would LOVE to get my hands on their 3d model and run it through my FEA software.
Thank you. Another good response about CF. Some of my favorite failures was when we tested fuselage burst strength and breaking wings. Good times when you get to destroy an aircraft on purpose. Carbon fiber is great and fails spectacularly. Basically zero yield unlike metal structures. It is very strong until it isn’t...

I worked on the tooling for the 787 fuselage. The mandrel was like a puzzle box that could retract in to itself.
Not sure what type of tooling this guy used. I doubt they were as clever as we uninspiring 50 year old white guys.
I never worked on yachts before. Do they really use pre-preg lay ups? I would assume chopper guns or wet layups.

I sat in the pilots seat for a few minutes in the early 2000’s.

It was Decommissioned 2008 IIRC.
FASCINATING THAT!
Wow. That’s a big autoclave. I would hate to pay the insurance rates on that facility...
Have watched a couple composite wings tested to failure. It’s very exciting. It’s also pretty dangerous because there can be razor sharp shards flying around when things fracture. Best to be not be too close.
