Abstract
A rod-shaped FRP bar is manufactured with a fiber and a resin by using a nozzlewhich includes an outer nozzlehaving a penetration hole at its center and a plurality of middle nozzlesdisposed at an inlet of the outer nozzleso 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 barhaving a section in which the fibers configure a plurality of fiber distribution layers from the center of the FRP bar toward the outside.
