[PSUBS-MAILIST] Titan submersible missing at Titanic site

[Alan James via Personal_Submersibles]

I was thinking about the carbon fibre hull & wondered whether the heat differential from the outside to the inside on the 5" thick hull had anything to do with the Titan crushing.At the wreck the water temperature is around 3°C & inside the sub it may be 24C (guessing). The carbon fibre is a great insulator so the outer face of the hull could be relatively stiffer due to the cold & take up more of the pressure than the more softer inner layers. Through cycling the outer layers could weaken. This would be unique to the submarine environment because I dont know anywhere else they would use 5" thick carbon fibre in freezing temperatures.Alan
