Abstract:
A rod-shaped FRP bar is manufactured with a fiber and a resin by using a nozzle (100) which includes an outer nozzle (11) having a penetration hole at its center and a plurality of middle nozzles (12) disposed at an inlet of the outer nozzle 11 so that one middle nozzle is located inside another middle nozzle with an interval. 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 (1) having a section in which the fibers configure a plurality of fiber distribution layers from the center of the FRP bar toward the outside.
