PURPOSE: To provide a manufacturing method for a fiber-reinforced thermosetting resin composite pipe, hardly rolling a void into an interface and never generating the separation of interface even when the pipe is used for a long period of time while excellent in the dimensional accuracy of the inner and outer diameters as well as the thickness thereof. CONSTITUTION: A multi-layer tube type body is formed by winding a belt type body A2, in which thermosetting resin is retained by continuous fibers arranged lengthwisely, around an extrusion molded thermosetting resin tube B2 in the circumferential direction substantially to laminate fiber-reinforced thermosetting resin layers while the multi-layer tubular body is heated under the atmospheric conditions of pressurization of inside atmosphere or evacuation of outside atmosphere or both of them to weld the thermosetting resin tube to the fiber reinforced thermosetting resin layers by fusion and, thereafter, they are integrated and fixed. The extrusion molded thermosetting resin tube B2 is cooled and solidified once, then, the belt type body A2 is wound around the thermosetting resin tube B2 under a condition that the tension of 100-5,000gr/cm<2> is retained. |
