ABSTRACT:
Using a fiber reinforced thermoplastic resin, component materials of shapes obtained by partitioning the shape of the desired hollow article into a plurality of parts are molded. Reinforcing members 5, made of a prepreg wherein reinforcing fiber is impregnated with thermoplastic resin, are affixed to the junctions of these component materials 1. These are housed within mold 7 as a hollow provisional assembly and a joined unitary body is formed by adding pressure and heating. Using the method of the present invention, it is possible to efficiently manufacture a complicatedly shaped hollow article, the obtained molded article being one which excels in mechanical strength and, moreover, has a surface which is continuous and smooth.
