Interesting video to test at what pressure different materials fail in a pipe section which have the same dimensions.
Material, Weight (grams), Fail Pressure (kilograms)
Acrylic 9g 1538 kg
PVC 11g 1004 kg
Carbon Fiber 11g 2998 kg
Aluminum 20g 3840 kg
Titanium 33g 9190 kg
Brass 45g 2568 kg
Steel Seam Pipe 58g 4750 kg
Stainless Steel 59g 15800 kg

Re: Materials failing under pressure
The idea was good, but I would not trust these numbers.
The materials may be damaged long before the max weight has been shown.
You can even see it. Aluminium for example already deformed quite a bit at the top and the number still got bigger. But this much deformation can't still be in the elestic zone. And the moment the material is in the plastic deformation zone, it's done.
And we don't know, much about the materials. Not all Alu is the same. Neighter is steel, as we all know. In carbon the differences may even be bigger. You can change a lot with the way the threads are woven in carbon. The resin and curing process has a big influence as well.
