Processing and Performance of Metal Fiber Reinforced High Temperature Superconductor


Aggregation of YBa2Cu3O7-x powder by compaction molding and sintering results in porous ceramic with poor mechanical properties and hence improving the ceramic properties using continuous stainless steel fibers have been studied. Fiber reinforced beam specimens (2% of fibers by weight) were prepared by modifying the standard processing method. Fibers were pretreated with silver to reduce the contamination of the superconducting matrix. The mechanical and electrical properties of the superconducting ceramic-fiber composite was evaluated at 77K. Continuous stainless steel fibers improved the performance of the superconducting ceramic.
