    摘要: 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.

    摘要: According to one embodiment of the invention, a co-cured resin transfer molding manufacturing method includes providing a tool having one or more tooling details and disposing one or more preforms proximate the one or more tooling details. The one or more preforms are either dry or binderized. The method further includes disposing a high permeability medium outwardly from the one or more tooling details, disposing a prepreg skin panel outwardly from the high permeability medium, disposing the one or more tooling details and the prepreg skin panel within the tool, injecting a resin into the one or more preforms, and curing the one or more preforms and the prepreg skin panel.
