Abstract

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.
