| abstract |
The present invention provides a method for producing a press-molded body, the method having: a step for placing a material X in a mold, a step for closing the mold and injecting a material Y, which is a kneaded material, into the mold after pressure has begun to be applied to part of the material X; and a step for cold-pressing the material X and the material Y in the mold to integrally mold these materials, wherein the material X is cut from a composite material M that includes reinforcing fibers FA having a weight-average fiber length Lw A and a thermoplastic resin R X , the material Y includes carbon fibers B having a weight-average fiber length Lw B and a thermoplastic resin R Y , Lw B <Lw A , and Lw A is 1-100 mm inclusive. |
