Title: Composite materials

Abstract: A superconductor composite comprising at least one longitudinally extending superconductor filament or bundle of sub-filaments, each filament or bundle of sub-filaments being surrounded by and in good electrical contact with a matrix material, the matrix material comprising a plurality of longitudinally extending cells of a metal of high electrical conductivity surrounded by a material of lower electrical conductivity, the high electrical conductivity material surrounding the at least one superconducting filament or bundle of subfilaments being interrupted by a radially extending wall of the material of the lower electrical conductivity, the arrangement being such that where at least two superconductor filaments or sub-filaments are circumferentially circumscribed by a single annulus of the material of high electrical conductivity, the annulus is electrically interrupted by a radially extending wall of the material of low electrical conductivity.
