Abstract
A fiber reinforced polymer rebar composition and a method of forming the rebar composition is described. The method includes the steps of feeding a first fiber and a second fiber simultaneously through a preforming guide into a resin impregnator, pulling the fibers through the 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 the resin of the resin-soaked hybrid fiber undergoes polymerization and cross-linking.
Claims12
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.
