  • Patent number: 10272619
    Abstract: A composite truss structure may have a first facesheet, a second facesheet, and a plurality of truss elements joined with the first facesheet and the second facesheet at nodes to form a one-piece structure. The composite truss structure may be formed by a method comprising preparing a dry fabric mold by: 1) placing a first dry fabric layer on a tool, 2) placing a first layer of fabric-loaded mandrels on the first dry fabric layer, 3) placing a second layer of the fabric-loaded mandrels on the first layer of fabric-loaded mandrels, and 4) placing a second dry fabric layer over the fabric-loaded mandrels. The method may further comprise infusing the dry fabric mold with a resin, and curing the resin to provide the nonflexible composite truss structure.

  • Patent number: 8636252
    Abstract: A unitized composite structure comprises a composite member having at least one integrally formed composite stiffener. At least one end of the stiffener includes a runout forming a substantially smooth transition between the stiffener and the composite structure. The stiffener and runout may comprise a crown, side walls, and base cap. The transition in the runout may include a width of the crown increasing, a height of the side walls decreasing, and the base cap splaying outwardly.
