A process for the production of a composite molded article (7) in which a core portion of a porous resin layer is present between surface portions of a fiber-reinforced resin and the whole of the composite molded article is integrated, the process comprising the following steps, (a) the mixture preparation step of preparing a particles-containing resinous mixture of a curable liquid molding resin with light-weight filler particles having an average particle size of 0.01 to 2 mm, the light-weight filler particles being a mixture of rigid particles and compressible particles, (b) the laminate preparation step of preparing a laminate of a reinforcing fibrous sheet (2,5)/separation sheet (1,4)/layer of the resinous mixture in the above step (a)/separation sheet/reinforcing fibrous sheet, (c) the impregnation step of centripetally pressing and centrifugally relaxing the laminate at least once each, and (d) (d-1) the step of heating the laminate to cure the resin to form the composite molded article, or (d-2) the step of heating the laminate to partially cure the resin to form a partially cured composite material having shape retainability, and then completing the curing of the partially cured composite material in a mold (23,24) to form the composite molded article. <MATH> |
