Abstract
The invention relates to composite reinforcing fibers infused or compounded with pulp fibers and/or nano-fibers. The composite reinforcing fibers are composed of polymer, e.g., polymer resin. The pulp fibers and/or nano-fibers impart improved tensile strength to the composite reinforcing fibers, as well as a resulting product formed by the fibers. The composite reinforcing fibers may be used in a variety of cementitious applications, wherein traditional reinforcing fibers are typically used.
