Hope is not a plan, Major. Every officer knows that.
Carbon fiber is strong in tension, weak in compression.
When the carbon fiber is containing internal pressure relative to its environment, it is in tension.
When the carbon fiber is resisting external pressure relative to its interior, it is in compression.
Therefore, a carbon fiber aircraft hull is strong. A carbon fiber submarine hull is weak.
“Carbon fiber is strong in tension, weak in compression.”
I’m wondering how using a monocoque technique would change those dynamics.
My main experience is with carbon fiber windsurfing equipment and bicycles. My 12 pound road bike frame has 30k+ miles carrying my 225lb butt around with no issues, and when monocoqued windsurfing booms came out I stopped breaking them.
