Fiber-reinforced resin molded body, and manufacturing method therefor

A method for producing a molded body of a fiber reinforced resin, the method comprising:

• laminating and disposing, inside a mold, a first fiber reinforced resin and a second fiber reinforced resins, the first fiber reinforced resin including a plurality of reinforcing fibers arranged to be aligned in one direction and a matrix resin, the second fiber reinforced resins including blocks each including a plurality of reinforcing fibers arranged to be aligned in one direction and a matrix resin, the blocks each having a smaller size than that of the first fiber reinforced resin, the blocks being randomly aggregated;
• and
• molding, inside the mold, the disposed first fiber reinforced resin and the disposed second fiber reinforced resins,
• wherein
• the mold includes a cavity section for molding a molded body in the molding, the molded body including a rib portion, and
• in the disposing, the first fiber reinforced resin is disposed on the second fiber reinforced resins on a side of the cavity section.
