US 5,399,424 A · Fibrillated pultruded electronic component

Abstract

A method for manufacturing a fibrillated pultruded electronic component includes the steps of providing a rod comprising a plurality of conductive fibers embedded in a matrix material, the rod having a first end and a second end. The rod is rotated and a liquid is sprayed onto the rod at a distance from the first end of the rod. The matrix material is abraded away from between the fibers of the rod. The fibers of the rod are then cut. A disk is formed which has a plurality of conductive fibers embedded in a matrix material. However, the ends of the disk include only the conductive fibers and not the matrix material. This enables the ends of the disk to have a fibrillated brush-like structure which is particularly well suited for low energy electronic/microelectronic signal level circuitry typified by contemporary digital and analog signal processors.
