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.
