I think the behavior of the material is probably more understood when it's internal pressure vessel. I think in general that's a much more understood problem and carbon fibre probably is perfectly fine for that sort of vessel. Similar to how a thin aluminum can of beer can be pressurized quite high, but it'll quickly buckle when poked on the outside.
