Whats your opinion on the tufnol 1P/13
I'm looking to layer it on various various piezoelectric components. I'm testing these piezo components with an electro mechanical testing system but the "sheets" i lay on the top/bottom of these components cannot be conductive and withstand large forces (up to 10kN) at various frequenciesGenerally not as good as the other ones for more demanding engineering applications .
Tell me a bit more about what you need this material for and I can probably give a more detailed answer .
Is the 35MPa hydrostatic pressure or the axial pressure applied to a stack of components in a press ? If it is in a press then preventing extrusion of the sheet may be a problem.I'm looking for a non-conductive material that can withstand pressures up to 35 MPa or about 5000 psi.
Its axial pressure by a press and no need to consider acoustic impedance. I think the suggestion for Tufnol is the best. What is your opinion on the material?Is the 35MPa hydrostatic pressure or the axial pressure applied to a stack of components in a press ? If it is in a press then preventing extrusion of the sheet may be a problem.
You might also consider testing pairs of piezoelectric components in opposition. That would electrically ground the outside of both units. In the same way a ceramic plate or a disconnected piezo element could be used as an insulator.
Do you need to consider acoustic impedance matching in the choice of material ?
