Why OceanGate Titan Imploded - A Carbon Fiber Composites Perspective

This video is a bit of a break from the norm on this channel as I usually enjoy talking about nature, skiing etc but as someone who has worked with composite fibres like carbon fibre for over 10 years I was absolutely shocked at the engineering and assembly practices of the Oceangate Titan submersible. In this video I wanted to discuss a few of the things I have observed in the construction which may have lead to the catastrophic failure of the pressure hull and subsequent tragic loss of life. This is of course all just my speculative opinion and is not fact. Much of my composites knowledge is self taught and empirical and I would not claim to be an expert in any way. I also do not do not wish to offend anyone who may have been affected by this event. Thoughts go out to the victims and families involved. 00:00 - Intro 00:37 - What failures may have caused the Implosion 01:05 - Design flaws in the carbon fibre pressure hull design 02:26 - Mechanisms of carbon fibre failure 03:01 - Audible cracks in the carbon fibre pressure hull 03:58 - What I think the pressure hull should have looked like 04:14 - Strength to buoyancy ratio? 04:40 - Glue bond between the carbon hull and Titanium interface cap 05:33 - Why you don't degrease components without gloves on 06:20 - Where is the clean room for the hull assembly? 06:49 - Was the glue mixed and applied correctly? 09:26 - No glue squeeze out from join when assembled? 09:40 - The bonding equipment I would have used 10:03 - How to bond dissimilar materials like Titanium and Carbon fibre 10:47 - What can we learn from the imploded Titan wreckage 12:16 - Composites could work but need way more testing
