Abstract

A fiber reinforced resin molded body; including: resin-integrated carbon fiber sheetsthat are stacked and unified, each of the resin-integrated carbon fiber sheetsincluding a carbon fiber sheetand at least one resinselected from the group consisting of thermoplastic resin and thermosetting resin. The carbon fiber sheetincludes a unidirectional long-fiber groupspread and arrayed in one direction, and multidirectional fibersandderived from the unidirectional long-fiber group. The multidirectional fibersandcross carbon fibers constituting the unidirectional long-fiber group. The fiber reinforced resin molded body is a molded body of two or more stacked layers of the resin-integrated carbon fiber sheets, or a molded body of the resin-integrated carbon fiber sheetthat is stacked with a resin-integrated carbon fiber sheet including a different carbon fiber sheet. Thus, the present invention provides a fiber reinforced resin molded body including a surface-modified carbon fiber sheet and thus having high interlaminar fracture toughness, and a method for producing the carbon fiber sheet for the fiber reinforced resin molded body.
