Abstract

Provided are a method for manufacturing a molded article consisting of a fiber-reinforced composite material containing a cured product of a thermosetting resin or a thermosetting resin composition and continuous reinforcing fibers, the method including, in this order, Steps (I) to (III) described below, a resin impregnating apparatus suitably used for the manufacturing method, and a 3D printer. Step (I): A coating step of coating a surface of a continuous reinforcing fiber bundle with a thermosetting resin or a thermosetting resin composition. Step (II): A resin impregnating step of twisting the continuous reinforcing fiber bundle after step (I) and obtaining a prepreg impregnated with the thermosetting resin or the thermosetting resin composition. Step (III): A heating and molding step of disposing the prepreg obtained in step (II) above and then heating the prepreg.
