He was an expert on surface naval construction and the Titanic. He was not a subject matter expert in submarine vehicle construction - and several such SMEs plus those who are in the carbon fiber fabrication industry have commented about the bad layup technique chosen.
“He was an expert on surface naval construction and the Titanic”
I referred to him as a Titanic expert.
OTOH, as a veteran of over 35 deep sea dives to the Titanic he should have noticed something.
“and several such SMEs plus those who are in the carbon fiber fabrication industry have commented about the bad layup technique chosen.”
The cross layup is required with fabric that has single direction fibers. These rolls are manufactured with fiber patterns designed for particular uses.
I haven’t seen any of the comments you refer to.
