1. A method of forming a rebar composition, comprising:
feeding a first fiber and a second fiber simultaneously into a resin impregnator, thereby forming a hybrid fiber, wherein the first and second fibers are different;
pulling the fibers through a liquid polymeric resin in the resin impregnator to form a resin- soaked hybrid fiber; and
passing the resin-soaked hybrid fiber through a heated stationary die, where resin of the resin- soaked hybrid fiber undergoes polymerization and cross-linking to form a fiber reinforced polymer rebar,
wherein a polymer is present in the fiber reinforced polymer rebar in an amount ranging from 35 to 43 wt % based on a total weight of the rebar wherein the rebar has a ductility ratio of at least 30% greater than a reference rebar comprising of one fiber.
