Abrégé

Systems and methods are directed to a pull-through winding method, and a manufacturing fixture, or mandrel, that guides the layup of material in the pull-through winding method, for fabrication of a three-dimensional load bearing structure. These systems and methods allow fibers of material of the 3D load bearing structure to be pulled as straight as possible during winding, and maintained as straight as possible during curing, to take full advantage of properties associated with the fiber or filament-based materials used in these structures, including, for example, carbon fiber material. The manufacturing fixture includes a plurality of pull-through slots at end portions thereof, that provide for the pulling of the fiber-based material, and the application and maintenance of tension in the material that maintains the alignment of the fibers as the material is wound, cured and hardened.
