Abstract: The present invention provides an assembly of molding materials, each of which is obtained by covering a carbon fiber bundle that contains an impregnation assistant with a thermoplastic resin. This assembly of molding materials is configured such that 30% or more of the whole assembly is a molding material that satisfies 100?F/L (N/m), where L is the molding material length in the axial direction of the carbon fiber bundle and F is the grip force of the carbon fiber bundle with respect to the molding material. Consequently, falling-off of carbon fibers from the molding materials during injection molding is able to be prevented, so that a molded body is able to be produced with high production efficiency.

Abstract: A press-molded product includes: carbon fibers having a weight average fiber length of 1 mm or more; a polyamide-based resin (X); and a polyarylene ether-based resin (Y). The carbon fibers include carbon fiber bundles. The polyamide-based resin (X) and the polyarylene ether-based resin (Y) form a sea-island structure inside and outside the carbon fiber bundles. In the sea-island structure, one of the polyamide-based resin (X) and the polyarylene ether-based resin (Y) forms a sea phase and the other forms an island phase having a particle diameter Dr of 0.05 ?m or more and less than 50 ?m.
