PURPOSE: To inexpensively and efficiently produce a composite molded product having a sandwich structure by utilizing a recovery article of an FRP composite molded product while contributing to an environmental problem.
CONSTITUTION: A reinforcing fibrous sheet (or a laminated sheet containing the same) is continuously supplied and a resin mixture containing crushed matter of a composite molded product recovery article and a liquid molding resin is arranged on the sheet in a laminar form (a) and, continuously, the reinforcing fibrous sheet (or the laminated sheet containing the same) is supperposed on the layer of the resin mixture so as to sandwich the resin mixture (b). Subsequently, pressure is applied to this laminate from above and below to infiltrate the liquid molding resin into the reinforcing fibrous sheet so as to allow the same to reach the surface layer part of the laminate and air bubbles present in the fibrous sheet are expelled out of the system to sufficiently wet the fibrous sheet with the liquid molding resin (c) and the laminate thus impregnated is continuously introduced into a heating zone in a planar state to cure the resin (d).
