1. A manufacturing apparatus for a fiber reinforced polymer (FRP) bar, which includes a fiber winding reel (101), a resin supplier (102), a nozzle (100) and a drawer (105) and manufactures a rod-shaped FRP bar with a fiber and a resin,
wherein the nozzle (100) includes a tapered outer nozzle (11) having a penetration hole formed at its center and having an inlet with a greater sectional area than an outlet of the tapered outer nozzle (11), and a plurality of middle nozzles (12) disposed at the inlet of the tapered outer nozzle (11) so that one middle nozzle is located inside another middle nozzle with an interval, wherein a plate-shaped guide member (200) is disposed in front of an inlet of the nozzle (100), wherein the plate-shaped guide member (200) has penetration holes extending in a circumferential direction and intermittently formed along the circumference at locations corresponding to any one or all of the intervals between the tapered outer nozzle (11) and the middle nozzle (12) and between the middle nozzles (12), wherein connection rods (130) are disposed at the rear surface of the plate-shaped guide member (200) so that the connection rods (130) are coupled to the tapered outer nozzle (11) and the plurality of middle nozzles (12) and the plated-shaped guide member (200) is coupled to the nozzle (100), wherein fibers are supplied to the inlet of the nozzle (100) through the penetration holes of the plate-shaped guide member (200), and wherein fibers are supplied through a center hole of the middle nozzle located at an innermost location, through intervals between the middle nozzles and through intervals between the middle nozzles and the outer nozzle, thereby making a hybrid FRP bar having a section in which the fibers configure a plurality of fiber distribution layers from the center of the FRP bar toward the outside. |
