A fiber reinforced resin hollow molded bodyin which a resin-integrated fiber sheet is used. The resin-integrated fiber sheet includes unidirectional continuous fibers that are spread fibers of a continuous fiber group and arrayed unidirectionally in parallel, and thermoplastic resin that is present at least on a surface of the unidirectional continuous fibers. In the hollow molded body, in a state where the resin-integrated fiber sheet or a plurality of the resin-integrated fiber sheetsare stacked, the resin-integrated fiber sheet or the plurality of resin-integrated fiber sheets are wound to produce a wound body having an overlapping portion. The thermoplastic resin is impregnated in the unidirectional continuous fibers. The resin-integrated fiber sheet or the plurality of resin-integrated fiber sheets are consolidated.

Fiber-reinforced resin hollow molded body and method for producing same

A resin-integrated fiber sheetfor vacuum forming for producing a fiber reinforced resin molded body through vacuum forming includes: unidirectional continuous fibersthat are spread fibers of a continuous fiber group and arrayed in parallel in one direction; bridging fiberslying in directions crossing the unidirectional continuous fibers; and thermoplastic resinpresent on part of the surface of the unidirectional continuous fibersto unify the unidirectional continuous fibersand the bridging fibers. A fiber reinforced resin molded body of the present invention is a vacuum formed body in which two or more of the resin-integrated fiber sheetsare stacked. A method for producing the molded body of the present invention includes subjecting the resin-integrated fiber sheetsto vacuum forming from a lower mold with a vacuum line and pressurizing the sheets with compressed air from an upper mold. Thus, the present invention provides a resin-integrated fiber sheet for vacuum forming having excellent shapeability and avoiding voids, a molded body including the same, and a method for producing the molded body including the same.
