Abstract
Methods and articles for reinforcing castable compositions through the use of reinforcing elements maintained in a close-packed alignment in a dispersible containment means.
Claims16
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.

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
- 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.
