    摘要: Static eliminator device includes a nonmetallic pultruded composite member having a plurality of conductive carbon fibers provided within a polymer matrix of thermosetting resin, wherein the plurality of carbon fibers are oriented within the polymer matrix in a longitudinal direction of the pultruded composite member and extend continuously therethrough. The pultruded composite member has at least one laser fibrillated end including a brush-like structure of densely distributed filament contacts formed from an exposed length of the carbon fibers for contact with the surface. The brush-like structure has either a straight edge configuration or a shaped configuration. The static eliminator device may include a base member for holding the pultruded composite member, wherein the base member electrically communicates with the plurality of conductive fibers to permit the electrical charge to pass therefrom. The static eliminator device utilizes a plurality of the pultruded composite members attached to the base member, each having a rod shape, or a single pultruded composite member having a planar shape. Alternatively, the static eliminator device may essentially be of single piece construction, wherein the pultruded composite member is planar in shape.

    摘要: A contact for use in contacting a moving photoreceptor surface, is formed from a structure (preferably a pultrusion) including a plurality of continuous strand fibers of high electrical resistance, and a thermally stable insulating component between the resistive fibers. The resistive fibers are configured to form a brush extending from the insulating component for contact with the photoreceptor surface. The resistance of the fibers is sufficiently high to reduce leakage of surface charges away from the photoreceptor and to provide a high resistance between adjacent fibers. The insulating component, which serves to interface the carbon filaments from each other and from a host polymer may comprise an organic compound, such as a polyimide composition, or may comprise an inorganic compound such as Al.sub.2 O.sub.3 or water glass, and is thermally stable below about 1000.degree. C. The host polymer, on the other hand volatilizes rapidly and cleanly upon direct exposure to laser energy.
