Abstract
A process for the production of a composite molded article having two surface layer (skin) portions of a fiber-reinforced resin (FRP) and a core portion of a porous resin layer between the two surface layer portions, all of which portions are integrated. More specifically, the invention relates to a process for the production of a light-weight and tough composite article having a foamed core-sandwiched structure in which two dense surface layer (skin) portions of a fiber-reinforced resin and a core portion of a porous resin layer having numerous air foams are integrally molded such that the core portion is integrated between the above two dense surface layer portions. This process can be carried out at a low cost by a batch or continuous method.
