I’m absolutely not an engineer, but from what I read, the first and most basic mistake was not getting the carbon-based material tested to see if it would resist the deep-sea pressure. Apparently it didn’t.

My understanding is that the carbon fiber worked for a few dives but over time became "fatigued". That's according to James Cameron, director of "Titanic" and a veteran of many dives in the deep, including the Mariana Trench. Cameron noted that the fact that there were mixed materials (carbon and resin) made it ultimately unsafe.
