A method for producing a reinforcement rod from a fibrous composite material comprising continuous mineral fibers and at least one resin, the resin being mixed with the dry mineral fibers, then wrapped with a strand of material, and the resin then being instantaneous or nearly instantaneously cured (e.g., snap cured) to form an optionally round rod with an optionally helical rib. In aspects, a mixture comprising an environmentally friendly and zero or low volatile organic compound (VOC) emitting resin and a resin-curing agent mixture is used. In aspects, helical ribs are added to the surface of the rod in a manner not to disrupt the longitudinal orientation of the core reinforcing mineral fibers. In aspects, ultraviolet irradiators are used to snap cure the reinforcement. When cured, corrosion resistant mineral fibers are encapsulated in a corrosion resistant matrix. The process allows for a simplified, condensed, and single operation for producing a corrosion resistant fibrous composite reinforcement rod.

A method for producing a reinforcement rod from a fibrous composite material comprising continuous mineral fibers and at least one resin, the resin being mixed with the dry mineral fibers, then wrapped with a strand of material, and the resin then being instantaneous or nearly instantaneously fully cured (e.g., snap cured) to form an optionally round rod with an optionally helical rib. In aspects, a mixture comprising an environmentally friendly and zero or low volatile organic compound (VOC) emitting resin and a resin-curing agent mixture is used. In aspects, helical ribs are added to the surface of the rod in a manner not to disrupt the longitudinal orientation of the core reinforcing mineral fibers. In aspects, ultraviolet irradiators are used to snap cure the reinforcement. When fully cured, corrosion resistant mineral fibers are encapsulated in a corrosion resistant matrix. The process allows for a simplified, condensed, and single operation for producing a corrosion resistant fibrous composite reinforcement rod.
