Abstract
PURPOSE: To easily mass-produce reinforced resin tubular bodies whose inner configuration is complicated, by forming a reinforcing resin molding material layer around a core mold having a synthetic resin foamed body on the outer surace layer followed by the curing of the reinforcing resin molding material layer.
CONSTITUTION: A reinforcing resin molding material made up of a glass fiber reinforcing material and a low-temperature curing unsaturated polyester resin liquid is wound around the tubular foamed body 1 of the core mold to form the reinforcing resin molding material layer 5, which is cured by heating it at a temperature at which the foamed body 1 constituting the core mold would not be deformed to produce the reinforced resin tubular body 6. A rotating shaft 3, a support 4, setting members 2, etc. are removed to obtain the reinforced resin tubular body 6 with the tubular foamed body 1 retained therein, and the tubular body 6 is heated with steam from the outside so that the tubular foamed body 1 can be shrinked. Then as a gap 7 is formed between the reinforced resin tubular body 6 and the tubular foamed body 1, eityer the foamed body that has been shrinked is removed as it is or it is removed after it is broken to get the reinforced resin tubular body 6.
