Abstract: A method for the manufacture of low cost "oriented" composite molding compounds using discontinuous fibers embedded in a resin matrix. The method involves the steps of aligning discontinuous fibers by use of a strong electric field while simultaneously inserting the fibers onto a polymer substrate comprised of an uncured resin matrix. A preferred embodiment includes the incorporation of a mesh or a glass capillary array located parallel and adjacent to the polymer substrate to further ensure fiber alignment. After the fibers are attached to the uncured resin matrix, the aligned fibers are forced to lie down parallel along the surface of the polymer substrate by mechanically forcing the fibers flat. The newly formed reinforced polymer films may then be stacked with the fibers of each ply oriented to achieve the desired mechanical properties, and then cured to produce an improved composite laminate which can be machined to form a high strength shaped member.
