PURPOSE: An FRP(Fiberglass Reinforced Plastic) water pipe using a reinforcing fiber is provided to effectually endure the internal pressure and load by additionally winding a reinforcing fiber on the outside of a connector and the front of the water pipe. CONSTITUTION: An FRP(Fiberglass Reinforced Plastic) water pipe using a reinforcing fiber is composed of an expanded part(102), a packing groove(103), a packing(110), and a pusher(120). The expanded part and the packing groove are molded by expanding one end of a synthetic resin pipe(10). The packing and the pusher are integrally inserted in the packing groove. The resin is provided from the outside of the synthetic resin pipe to the reinforcing fiber. The sand is combined to the resin and a molding device spirally supplies the synthetic resin while moving to the left. The molding device supplies the resin to the reinforcing fiber and spirally supplies the synthetic resin while moving to the right. The molding device winds the reinforcing fiber on the outside of the synthetic resin pipe.
