PURPOSE: To provide a molding material which can be used for the manufacture of a molding containing fibers as a reinforcing material in high density but highly dispersible in the case of injection molding, and besides, with significantly improved mechanical strength, especially impact strength, and almost free from fiber breakage. CONSTITUTION: This molding material A consists of a fibrous reinforcing material comprising a single fiber C and a thermoplastic resin B, with which an area between the single fibers C as the constituent unit of the fibrous reinforcing material, is impregnated, by application of the resin B to the periphery of the single fiber C. The molding material A is of the angular or columnar shape, and the fibrous reinforcing material packed in the molding material is equivalent to at least, 50wt.% and 90wt.% or lower. In addition, the fibrous reinforcing material is continuously arranged almost in parallel with an axial direction over the entire length of the molding material A. Further, the surface equivalent to 90% or higher of the single fiber C as the constituent unit of the fibrous reinforcing material is covered by the thermoplastic resin B, and every piece of the single fiber C is ideally dispersed in the thermoplastic resin B. |
