Abstract: A method of producing a continuous fiber reinforced bent resin pipe, including winding a continuous reinforcing fiber on the outer surface of a tube-like flexible core mold while such core mold is straight in shape, the flexible core mold which is straight when unloaded being capable of keeping a cross section defined in radial direction when the core mold is bent. The core mold on which the continuous fiber has been wound is then bent and placed into a cavity defined by an outer mold formed of split molds each having an inner surface forming the predetermined outer configuration of a bent pipe. A liquefied synthetic resin is caused to be cured between the outer and the core molds to integrate both the fiber and resin. Thereafter the molded product is removed from the outer mold and the core mold is removed from the molded product.
