PURPOSE:To shorten a molding time, to enhance quality and to facilitate work, by a method wherein reinforcing cloth wound in a coil form is inserted in a cylindrical mold from one end thereof and the mold is rotated around the axial line thereof and a liquid synthetic resin is injected in the mold and solidified. CONSTITUTION:Reinforcing cloth 2 wound in a coil form is inserted in a cylindrical mold in a horizontal state from one end thereof. when the mold 1 is rotated in a direction unwinding the cloth 2, the cloth 2 is closely contacted with the mold 1 in the state adhered to the inner peripheral surface thereof to become an accurate cylindrical shape. The reinforcing cloths 2 are superposed several times over according to the thickness of a pipe to be molded to form a cloth layer 3. Next, a resin feed-in cylinder 4 is allowed to penetrate into the mold 1 and a resin solution 6 is injected in the mold 1 from the leading end of said cylinder 4 so as to be applied to the reinforcing cloth layer 3 to form a reinforced resin wall. The mold 1 is rotated at a high speed and the injected resin solution 6 is equally added to the cloth layer 3 by centrifugal force and solidified. After curing, the molded one is taken out from the mold to obtain the product. |
