Improved fibrous structural reinforcements (16) for castable compositions (14) are provided and methods for making the same. In one implementation, the improved fibrous structural reinforcements rely 16) on an amorphous crystalline component (10), an isotactic crystalline component (12) and profiled terminal ends (20, 22) to improve flexural properties. The isotactic crystalline component (12) provides an initial strength to the fiber (16) and the amorphous crystalline component (10) provides a latent strength once the fiber (16) is subjected to tension and flexural input in the castable construct (14). The profiled terminal ends (20, 22) lock into a cured keyway (301) in the castable construct (14), thereby providing further enhancement to the tensile strength. |
