There is disclosed an electrical component for making electrical contact with another component comprising a composite member including a plurality of electrically conductive, nonmetallic fibers in an electrically conductive metallic matrix wherein said composite member has an axial direction and a DC volume resistivity of less than about 100 micro ohm cm, said plurality of conductive fibers being oriented in said matrix in a direction substantially parallel to each other and to the axial direction of said member and said fibers being continuous from one end of said member to the other end to provide a plurality of electrical contact points at each end of said member, at least one end of said member having a brush-like structure of said plurality of fibers wherein said brush-like structure is at least substantially free of the metallic matrix, thereby providing a distributed filament contact wherein the terminating ends of the fibers in the brush-like structure define an electrically contacting surface.
An electrical component for making electrical contact with another component comprising a composite member including a plurality of electrically conductive, nonmetallic fibers in an electrically conductive metallic matrix selected from the group consisting of metals and metal alloys, wherein said composite member has an axial direction and a DC volume resistivity of less than about 100 micro ohm cm, said plurality of conductive fibers being oriented in said matrix in a direction substantially parallel to each other and to the axial direction of said member and said fibers being continuous from one end of said member to the other end to provide a plurality of electrical contact points at each end of said member, at least one end of said member having a brush-like structure of said plurality of fibers wherein said brush-like structure is at least substantially free of the metallic matrix, thereby providing a distributed filament contact wherein the terminating ends of the fibers in the brush-like structure define an electrically contacting surface.
An electrical device for conducting electrical current comprising two contacting components at least one of said components being a composite member including a plurality of electrically conductive, nonmetallic fibers in an electrically conductive metallic matrix selected from the group consisting of metals and metal alloys, wherein said composite member has an axial direction and a DC volume resistivity of less than about 100 micro ohm cm, said plurality of conductive fibers being oriented in said matrix in a direction substantially parallel to each other and to the axial direction of said member and said fibers being continuous from one end of said member to the other end to provide a plurality of electrical contact points at each end of said member, at least one end of said member having a brush-like structure of said plurality of fibers wherein said brush-like structure is at least substantially free of the metallic matrix, thereby providing a distributed filament contact wherein the terminating ends of the fibers in the brush-like structure define an electrically contacting surface.
