Provided are: an FRP sheet press molding method and device whereby yield can be improved without opening/closing adjustment of a mold after mold clamping; and an FRP molded article. The FRP sheet press molding method, whereby a press-molded article PM is molded using a fiber-reinforced plastic sheet material SM, comprises: a press step in which moldsare closed and the heated sheet material SM is press-molded inside a cavity; and a filling step in which the closed state of the moldsis maintained from the press step, a molten resin MP is pressure-injected into a gap IS that occurs between the sheet material SM and the cavity, and a surface of the sheet material SM and a surface of the molten resin MP are caused to come in contact with the cavity

FRP sheet press molding method and device and FRP molded article

A fiber-reinforced resin molded article is molded into a three-dimensional shape on the basis of a sheet-shaped base material containing a fiber-reinforced resin. The fiber-reinforced resin molded article includes three-way directed corner portions constituted by plate sections joined in three mutually different directions. The fiber-reinforced resin molded article includes wrinkles that protrude from the differently directed corner portions by folding the sheet base material, and thick-walled sections which are laminated at sites where at least the wrinkles are formed.
