METODO DE FABRICACION PARA MATERIAL COMPUESTO Y APARATO DE FABRICACION PARA MATERIAL COMPUESTO.

[Problem] To provide a composite material production method that, by controlling the flow of resin in a cavity, can shorten a formation period and can reduce equipment investment costs. Also to provide a composite material production device, a preform for a composite material, and a composite material. [Solution] A production method for a composite material 400 that is provided with a reinforcing substrate 510 and a resin 600 with which the reinforcing substrate has been impregnated. The production method has: an application step wherein an adhesive 520 is applied to the reinforcing substrate, which is in sheet form and comprises a first region 501 and a second region 502, such that the density of the adhesive in the second region is lower than the density of the adhesive in the first region; a preformation step wherein a preform 500 is formed by preforming the reinforcing substrate; and a step wherein the preform is impregnated with the resin 600 and the composite material 400 is formed. The resin, which is injected into a cavity 350, is made to flow more easily at the portion of the cavity at which the second region of the reinforcing substrate is arranged than at the portion at which the first region of the reinforcing substrate is arranged.
