  • Aligned discontinuous fiber preforms, composites and systems and processes of manufacture
    Patent number: 11047078
    Abstract: A process for aligning discontinuous fibers, and composite products and mats comprised of highly aligned discontinuous fibers, including products of the process. Aligned discontinuous fiber composite products include a matrix of fibers, each fiber having a longitudinal fiber axis, the composite comprising a free, uncut edge extending along an edge axis. The longitudinal fiber axis of a majority of the fibers in the composite product are aligned within a predetermined alignment tolerance of an alignment axis non-parallel to the edge axis. Aligned discontinuous fiber mats may have a first areal density of fibers in a first region of the composite located inward relative to the free, uncut edge, and a second area density at or adjacent to the free, uncut edge.
    Type: Grant
