PURPOSE: To facilitate the connection work to a joint, to enhance the reliability of connection strength and to prevent not only the generation of a cut powder at the time of the formation of a screw part but also the reduction of fiber reinforcing effect. CONSTITUTION: A fiber reinforced thermoplastic resin composite pipe 15 is obtained by laminating and welding a thermoplastic resin inner layer 2, a first reinforcing layer 3 composed of a thermoplastic resin containing a continuous reinforcing fiber oriented in a pipe axial direction, a second reinforcing layer 4 composed of a thermoplastic resin containing a continuous reinforcing fiber spirally oriented in a pipe axial direction and a thermoplastic resin outer layer 5 and screw parts 14 are formed to both end parts of the thermoplastic resin outer layer 5. |
