For the past week, the world has been treated to a macabre piece of theatre: an international, multi-million-dollar operation to save the lives of five crewmen of the Titan submersible, who – it now turns out – were almost certainly known to have died from the start. Life is sacred. Who could object to any expense to save just a single soul? But if all life is indeed sacred, then some lives are clearly more sacred than others.
This dufus decided on probably the worst composite material to use for a compressive load. Carbon fiber is very strong under high tensile load, it’s used all the time for pressure vessels where the pressure is inside the vessel. Compressive loads, not nearly as much (as little as 10% the tensile strength of the same material). See https://www.sciencedirect.com/topics/materials-science/carbon-fiber-properties
