A composite cruciform structure adapted for securely joining two or more intersecting fiber based composite structural members of an airframe and the like, is disclosed. A first bundle of graphite or other fibers of high strength is intimately interwoven with a second bundle of like fibers, with each bundle of fibers extending in a different direction and being aligned with the general longitudinal axis of a respective first and second composite structural member. A third bundle of fibers is interwoven with both the first and second bundles of fibers to form the cruciform structure. The bundles of fibers are reinforced with a suitable cured resin. The cruciform structure may comprise an integral part of the respective structural members, or may be attached thereto by splicing. The cruciform allows for substantially even distribution of structural loads regardless of the direction of the corresponding load force vectors, and is most advantageously utilized in the construction of high strength and low weight airframes.
