1. A method for manufacturing a molded product of a laminated substrate, the method comprising:
(1) heating a prepreg substrate including reinforcing fibers and a thermoplastic resin to a temperature higher than or equal to the melting point or the glass transition point of the thermoplastic resin that constitutes the prepreg, and then laminating a sheet material having a porosity of from 50% to 99% on at least one surface of the prepreg substrate to thereby obtain a laminated substrate, or (2) laminating a sheet material having a porosity of from 50% to 99% on a prepreg substrate including reinforcing fibers and a thermoplastic resin on at least one surface of the prepreg substrate, and then heating the laminate thus obtained to a temperature higher than or equal to the melting point or the glass transition point of the thermoplastic resin that constitutes the prepreg to thereby obtain a laminated substrate,
the method subsequently comprising introducing the laminated substrate into a mold that is set to a temperature lower than or equal to the melting point or the glass transition point of the thermoplastic resin that constitutes the prepreg, and then stamping molding the laminated substrate.
