摘要： PURPOSE:To obtain the objective preform by winding a continuous reinforcing fiber around a core mold, winding a hot-melt fiber web tape on the reinforcing fiber layer to obtain a formed article having a reinforcing fiber layer as the outermost layer and composed of a plurality of alternately laminated reinforcing fiber layers and hot-melt fiber layers and melting the hot-melt fiber with heat. CONSTITUTION:A continuous reinforcing fiber 2a (e.g. glass fiber) is wound around a core mold 6 and a hot-melt fiber web tape 4a (e.g. tape of a thermoplastic synthetic fiber such as vinyl acetate fiber) is wound on the reinforcing fiber layer to obtain a formed article having a reinforcing fiber layer 2d as the outermost layer and composed of a plurality of alternately laminated reinforcing fiber layers 2b, 2c and hot-melt fiber layers 4b, 4c. The formed article is heated to melt the hot-melt fiber, cooled and demolded from the core mold to obtain the objective preform containing the reinforcing fiber layers welded and integrated with each other by the hot-melt fibers. The formed article has high strength and rigidity in the orientation direction of the reinforcing fiber and is demoldable from the core mold without causing the collapse of the wound layers. It is suitable as a fiber-reinforced formed article such as automobile frame.
