PURPOSE:To produce a long fiber reinforced resin pipe effectively by a method in which while a tubular object is advanced along a mandrel, at least one of the tapelike or cordlike fiber composites made by holding thermoplastic resin on the continuous reinforcing fiber arranged in longitudinal direction are spirally wound on the outer periphery of said object and are welded to the tubular object. CONSTITUTION:The sheetlike fiber composite A1 made by holing thermoplastic resin on the continuous reinforcing fiber arranged in longitudinal direction from the side of the supported end, is fed to the mandrel 2 with circular shape in transverse section whose one end is supported, and by enclosing closely the mandrel 2, a tubular object A2 is obtained. Next, while said tubular object A2 is advanced in the state as it is along the mandrel 2, at least one of the tapelike or cordlike fiber composites B, C made by holding thermoplastic resin on the continuous reinforcing fiber arranged in longitudinal direction, are spirally wound on the outer periphery of said tubular object and is welded to the tubular object A2. Thus, a desired fiber reinforced resin pipe is obtained. |
