Reinforcing elements for castable compositions
US 5807458 A
1. A method of reinforcing a castable composition comprising the steps of:
introducing into a castable composition under dispersion conditions one or more dispersible fiber packages each comprising a plurality of polymeric fibers maintained in a substantially aligned arrangement by means of a perimeter wrap, said fibers being subject to entanglement when introduced loosely into said castable composition,
each of said fiber packages being substantially free of inter-fiber binding; and
controllably disrupting each of said packages to release fibers from each of said packages into said castable composition in a substantially unentangled manner.
2. The method of claim 1 comprising releasing essentially all of the fibers within an individual package substantially simultaneously in the form of individual fibers upon disruption of said package.
16. A method for reinforcing a castable composition comprising the steps of:
introducing into a castable composition under dispersion conditions a plurality of fiber packages releasably held together in the form of a dispersible unitized package,
each of said packages comprising a plurality of polymeric fibers maintained in a substantially aligned arrangement by means of a perimeter wrap, said fibers being subject to entanglement when introduced loosley into said castable composition
