PURPOSE:To make possible the automatic manufacture of a specified preform for FRP tube formation, with a stable quality by extracting the preform from a core material and returning the core material without the preform to a cylindrical film attaching step. CONSTITUTION:This method for manufacturing a preform for FRP tube formation consists of a cylindrical film attaching step which covers a core material S1 with a cylindrical film 21 and a step to transport the core material S1 covered with the cylindrical film 21 to a prepreg winding means 4. A prepreg P is arranged on the prepreg winding means 4, and is wound around the surface of the cylindrical film 21 used as a coat for the core material S1, using the prepreg winding means 4 to obtain a preform. Further, the preform is transported to a preform extraction means 3 with the core material S1. Next, the preform is extracted from the core material S1 using the preform extraction means 3. In addition, the step is provided with a step which returns the core material S1 extracted from the preform to a cylindrical film loading means 2. |
