<p>A lightweight beam (10) may have a triangular prism core (12) and a triaxial fabric cover (14) wrapped around the core (12), with at least one rod (16) proximate an apex of the core (12). The rod (16) may extend substantially parallel to a centerline (18) of the core (12). Multiple lightweight beams (10) may be joined to form a larger lightweight structure.</p> |
