Abstract
A formable matrix used as structural material and having an admixture of reinforcing non-metallic fibers to control deterioration and improve flexural strength. The fibers are fabricated with a cross section which provides a maximum ratio of surface to cross-sectional areas and increased frictional forces between fiber and matrix when the fiber is stressed. The disclosed embodiment of the fibers has a cross-sectional shape with a plurality of arms extending radially from the center, preferably with lobes formed at their outer ends.
Claims6
A structural material comprising a hardenable hydraulic-setting matrix and a plurality of randomly arranged elongated elements admixed in said matrix, said elements being fabricated of a non-metallic substance, the elements as a group extending in all directions in the formed and set matrix, each element having a cross section with a central area and a plurality of arms extending outwardly from said area, each element cross section being further provided with lobes on the outer ends of said arms.
