Abstract: A layered body which allows a reduction in residual volatile component and a method for producing the layered body. A reinforcing fiber composite material which has high heat resistance and superior mechanical strength and a method for producing the reinforcing fiber composite material. A method includes fusing together a plurality of layers each of which contains: a powder of an imide oligomer represented by a specific general formula; and reinforcement fibers.

Abstract: Provided is an injection molded body of a polypropylene resin composition, which has excellent fluidity and burr prevention performance. The polypropylene resin composition contains a conjugated diene-modified polypropylene resin (A) that has a melt flow rate of 1-150 g/10 min as measured at 230° C. under a load of 2.16 kg and a polypropylene resin (B) that has a melt flow rate of 7-100 g/10 min as measured at 230° C. under a load of 2.16 kg. Relative to 100 parts by weight of the total of the components (A) and (B), the content of the component (A) is 0.1-50 parts by weight and the content of the component (B) is 99.9-50 parts by weight. The polypropylene resin composition has a melt flow rate of 10-80 g/10 min as measured under the above-described conditions, while having a melt tension of 0.7-30 gf as measured at 200° C. at 10 m/min.
