@jukodebu Nobody designs anything by themselves. He spent millions on it so had a lot of help.

@mg6192 CF adds about 10% strength in compression, so they were basically diving in a plastic submarine. Forget about delamination or anything else.

@sharraleigh It's really hard to believe unless he was insane. I knew the difference between tension and compression and the basic physics involved in high school. He had an engineering degree from Princeton.

@VolkerHett I have some dynema fishing line that will hold 100lbs, but is not strong enough to support 2" of its own weight without bending over when held from the bottom. The CEO had a degree in engineering from Princeton, I don't know what he was thinking or why a billionaire wouldn't have done his own checks

@jeffchastain2977 Plastics don't do well under shear stress. I think that's what makes them plastics. It's sad

@Inktomei I learned all this stuff in my first year physics course in undergrad. Technically, it was covered in my high school physics class

@Maspets He did, but you have to watch one of his documentaries

@Inktomei No, but I leaned the difference between compression and tension and I understood how fiberglass works. CF is similar to FG. The glass is there to add tensile strength, not compression. I did learn about young and bulk modulus in hs physics. These are not exceptionally difficult concepts or math, I'm sure most grade schoolers could do it.
