I have a sheet of flexible Kevlar 16th of an inch thick coated on each side with a high temperature superconductor, what happens when you put hundred amp of current into each side, and then 1000 and so on. And I'm assuming that the superconductor is bonded very well to the Kevlar, and that it is at a temperature cohesive to it superconducting. Will the 2 sides repel each other? Turning the Kevlar into a rigid structure? How rigid? Please put in the layman's terms!
If we ignore that coating a Kevlar sheet with a high temperature superconductor is with current technology impossible one thing will happen:
It will rip the superconductor apart.
The Lorentz for such a high current at small distances is enormous. Here is a demonstration what happens: 5000 Amps through a copper bar.
