Patent number: 6773646Abstract: Exemplary mechanically-flattened fibers of the invention comprise generally elongate bodies having varied width or thickness dimensions and micro-diastrophic surface deformities. Preferred fibers are elongate synthetic polymer or multipolymer blend fibers for reinforcing matrix materials such as concrete, shotcrete, gypsum-containing materials, asphalt, plastic, rubber, and other matrix materials. Preferred methods for manufacturing such fibers comprise subjecting synthetic polymer fibers to compressive forces sufficient to achieve flattening and surface micro-diastrophism without substantially shredding and abrading the fibers. Further exemplary fibers and methods involve mechanically-flattening intertwined or braided fibers or fiber bundles, thereby providing fibers having physical impressions thereon of the intertwinement or braidingand, optionally though preferably of micro-diastrophic surface deformities.Type: GrantFiled: July 21, 2003Date of Patent: August 10, 2004Assignee: W. R. Grace & Co.-Conn.Inventors: Klaus-Alexander Rieder, Neal S. Berke, Stephen J. Fyler, Michael Macklin
