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.
