PURPOSE: To obtain a cylindrical molded item of FRP at a low rotational speed with high efficiency of molding, by pressing the surface of a material comprising a reinforcing material and a resin, which are fed onto the inner wall surface of a rotating cylindrical mold, by specified rolls so that the reinforcing material is impregnated with the resin and deaeration is effected.
CONSTITUTION: The cylindrical mold (A) is rotated at a speed at which a centrifugal force smaller than twice the gravity is generated, and a molding material is fed to the inner wall surface of the cylindrical mold (A) by a fiber reinforcing material feeding apparatus (D) and a liquid thermosetting feeding apparatus (E). The surface of the molding material is pressed by the press rolls (F) each having in the surface a plurality of recesses that are regular and/or irregular in shape but are not grooves so that the reinforcing material is impregnated well with the resin, deaeration is effected and molding is carried out.
