Abstract
A device for transferring electrical charge from an electrically conductive element to a rotating element is provided. The device has a body including a pultruded composite member having a multiplicity of electrically conductive fibers provided with a polymer matrix. The plurality of conductive fibers is oriented within the polymer matrix in a longitudinal direction of the pultruded composite member. The fibers each extend in a substantially parallel direction, parallel to a first axis. The body includes a first contact area. The body defines an aperture therein. The body has a second contact area on the periphery of the aperture spaced from the first contact area and a support. The support is secured to the body for supporting the body. The first contact area is for contact with the conductive element and the second contact area is for contact with the rotating element. The fibrillated portion is coincident with at least one of the first contact area or said second contact area.
