Abstract:
1. A matrix composition, comprising: a matrix material selected from the group consisting of adhesives, asphalt, composite materials, plastics, elastomers, and hydratable cementitious materials; and a plurality of individual fiber bodies having an elongated length defined between two opposing ends and comprising at least one synthetic polymer, said individual fiber bodies having surfaces that are substantially free of stress fractures induced by mechanical-flattening of the fiber bodies between opposed rollers, said individual fiber bodies being substantially nonfibrillatable into smaller fiber units after mixing in said matrix material to the extent necessary to achieve substantially uniform dispersal of the fibers therein, and said fiber bodies having a generally quadrilateral cross-sectional profile along said elongated length, thereby having width, thickness, and length dimensions wherein the average width is no less than 1.0 mm; wherein the average width is no more than 5.0 mm; wherein the average thickness is no less than 0.05 mm; wherein the average thickness is no more than 0.2 mm; wherein the average length is no less than 20 mm; and wherein the average length is no more than 75 mm.
