PURPOSE: To provide a method for manufacturing a reinforced foam which has a light weight, excellent rigidity and dimensional stability and in which the connection of a surface reinforced resin layer to an inner foamed resin layer is sufficient and no combustion residue retains in the case of incinerating. CONSTITUTION: A method for manufacturing a reinforced foam 10 comprises the steps of previously primarily orienting at least one surface of a foamed thermoplastic resin sheet 13 containing a thermoplastic resin and a foaming agent, then laminating the crosslinked thermoplastic resin sheets 22, 23, secondarily orienting the obtained laminated sheet 1 by heating, forming the sheet 23, and integrating the entire sheet 1. |
