The vessel imploded and from what I understand the sudden compression results in a diesel detonation whereby everything combustible is vaporized.
That could happen in a normal sub full of hydrocarbon vapor from grease, lubes (insert Navy joke here) etc, but the inside of this thing was pretty simple and clean. Air will heat up from adiabatic compression, but there probably wasn't any fuel for a detonation.

Human bodies could be fuel at that sudden temperature.

Due to overzealous captains.
So same damn reason.

Possibly, but you really need vapor for a compression detonation. I haven't burned a human body. Yet.

I honestly had no idea anyone had ever been to the Mariana Trench. That is absurd

No, they aren’t. You’re confusing toughness and strength. Toughness has a specific meaning when discussing material properties.

No, actually I'm not.
The tubs are made of CF as well. While the little parts like wings and bodywork, which are very thin, breaks easily the tubs most certainly do not.
CF is plenty tough.
I am not saying it was the proper material for the application.

How hot would that air get?

I believe the original descent to the Mariana Trench was in the 60’s, on the Trieste, which is insane for many reasons not the least of which it was built by Italians.

CF has its application and most certainly for non structural parts or structural parts that do not lead to catastrophic failure if they do fail. I could be wrong but I don't believe we will ever see CF used in commercial plane fuselages. There is a massive incentive to do so because of weight and subsequent fuel savings but the cost of a failure is just too high so CF is not used in this application. Plus planes see very cold temps at 36,000 feet and structural CF members do not do well through temperature (and pressure) cycles.
My only point is CF has it's application under the appropriate circumstances. Making a sub to travel 2.5 miles below the sea is not a good application for CF IMO, and in James Cameron's opinion.

"In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing."
You see a lot of carbon fiber structures with plastic deformation? Bent bicycle frames, for instance? Or do you see cracked and broken cf bicycle frames?

With a hell of a lot of assumptions about 2,390 degrees F.

Anyone with any common sense knew immediately that the sub was a crumpled tin can on the ocean floor.

And if you were hell bent on using it, it should have been used as the entire pressure boundary instead of having titanium end caps. But that would have been expensive, and apparently the billionaire skimped as much as possible on this.

This James Cameron guy sounds like he might know a thing or two about the ocean
