Cryogenic mechanical properties of low thermal expansion ZrW2O8 /epoxy composites and their application in impregnated REBCO superconducting coils
Rare-earth barium copper oxide (REBCO) coated conductor (CC) tapes are promising for high-energy and high-field applications. In epoxy-impregnated REBCO superconducting windings, during the cooling process, the delamination induced by thermal mismatch stress significantly threatens stable operation due to the weak c-...
