<p>A structural fabric (1) having a first fiber with a first ultimate strain and a second fiber with a second ultimate strain greater than the first ultimate strain, the first and second fibers being in the same plane. The invention is further directed to a structural fabric having a plurality of axial fibers and a plurality of first diagonal fibers braided with the axial fibers and oriented at a first braid angle relative thereto. The ultimate strain of the second fiber again being greater than the ultimate strain of the first fiber. Additionally, the invention is directed to a concrete beam (8) strengthened with the structural fibers of the present invention.</p> |
