Dittos. I was just a dirty-fingernail mechanical penguineer, working mostly in machine tools and then automotive process control, but even at that I was incredulous that anybody would use CF for a submarine hull. Still trying to imagine how they laid it up. No aerospace tape-layer I ever saw would do it.

“Still trying to imagine how they laid it up”

there’s a video of them laying it on that looks like a giant phonographic wax cylinder spinning slowly while a shuttle goes slowly back forth while the spinning cylinder pulls the fiber from a reel glue while glue coats the fiber ...

My recent background was in medical device manufacturing using a polymer and steel braid composite and it was dern near impossible to get rid of all the air bubble defects which if under pressure would magnify any defects by a magnitude of thousands or more.

The development process is long, expensive and tedious.

Apparently these dopes never had to deal with OSHA.

From another post...

“According to Weissman, Rush had bought the carbon fiber used to make the Titan “at a big discount from Boeing,” because “it was past its shelf life for use in airplanes.”

Doubt they kept it in temp controlled environment.
