The Bulk Superconductivity Group at the University of Cambridge has been able to address the problems of crack formation, growth and propagation in bulk (RE)BCO superconductors in the presence of large magnetic fields by introducing special reinforcing fibres into the material. The resulting composite materials structure resists internal mechanical forces, and acts as crack stoppers and inhibitors, allowing the material to take increased loads under large magnetic fields. The team is now seeking commercial partners to develop and implement the technology.
- Significant improvement in tensile strength, while maintaining superconducting properties
- Less temperature dependent than complex resin impregnation reinforcement methods
- Strong, compact (RE)BCO single grains
- Simple, scalable process
