Therefore, the crushing process of the waste FRP is quickened, and dust is less likely to be generated during the process. In addition, the fiber-containing solid material is surrounded by a thermoplastic plastic so that the fiber material is not exposed, which facilitates handling, and prevents moisture from penetrating inside, so that it can be stored in an open container and stored. Costs will be reduced. In addition, since the weight ratio of the FRP chip to the thermoplastic material is about 70%, a fiber-containing solid having a high fiber rate can be obtained, and the function as a filler can be enhanced. In addition, since the above-mentioned fiber-containing solids are mixed with a thermoplastic material and melted, and the melt is supplied to a mold and molded, the molded article is reinforced by a fibrous substance, and expanded by heat, Shrinkage is reduced. In addition, the above-mentioned fiber-containing solids are mixed with the thermoplastic material and melted, and the mixture is kneaded with a screw and supplied to the mold, so that the fibrous material is densely mixed into the thermoplastic and the metal is mixed. It is supplied to the mold and the strength of the molded product is further increased.
