Abstract: In the present disclosure, a method may include forming a three-dimensional composite fiber pre-form by three-dimensionally weaving a plurality of composite fibers. The composite fiber pre-form includes a plurality of open cells formed adjacent to and interlocked with each other, and a composite fiber forms at least a portion of a first side of a first open cell and at least a portion of a second side of a second open cell. The first open cell and the second open cell are adjacent to and interlocked with each other.

Abstract: A composite core with non-traditional geometries includes multiple elongate tubes arranged in a two-dimensional array. Each tube is made of a composite material. Each tube includes multiple curved sides. Each curved side inwardly curves toward a longitudinal axis passing through a geometric center of the tube to form a valley on an outer surface of the tube. An end of a first curved side connects to an end of a second curved side to form a crest on the outer surface of the tube. At least one crest formed on an outer surface of a first tube in the two-dimensional array contacts at least one valley formed on an outer surface of an adjacent second tube in the two-dimensional array.
