PURPOSE:To manufacture an FRP tube having a resistance to corrosion on its inner face by winding a resin-impregnated belt-shaped material with filler on a cylindrical mold, and winding a reinforcing continuous fiber body thereon, feeding heat-setting resin onto the reinforcing continuous fiber body and heat setting it. CONSTITUTION:A mold release film 14 is wound on a steel belt 24 wound helically on a rotating cylindrical mold, and unsaturated polyester resin 21 containing a curing agent is fed thereon. Then a glass paper 16 with glass flakes 19 on its surface is wound thereon with the upper accumulated surface facing on the mold side so that the glass flakes 19 are not dropped. Further, a glass roving cloth 28 as a reinforcing continuous fiber body is used for impregnating a wound material with unsaturated polyester resin 21 containing a curing agent and wound thereon. The wound material is carried to a curing oven 26 and cured, and then cut into the optional length by a cutter 29. An FRP tube not to be deteriorated by a chemical or the like can be manufactured by the process. |
