How does the gas get into this void between liner and overwrap? I presume the liner is meant to be impermeable? Or is it only impermeable when properly backed with the overwrap?
- tsuraan 10y agoThe helium COPV is submerged in LO2, so it's the oxygen that's soaking into the wrapping. I think the failure is that the oxygen is soaking into the wrapping before the helium is fully pressurized, and then the metal container expands slightly and crushes the oxygen that soaked in between the metal vessel and the carbon wrapping.
