Abstract

A molding method is provided for manufacturing a composite material having a base layer formed of at least one first prepreg sheet and a second prepreg sheet stacked on at least a portion of the first prepreg sheet. The first prepreg sheet and the second prepreg sheet are stacked, and then heated and cured. The second prepreg sheet constitutes a front surface layer that is integrally formed on the surface of the base layer. Here, the amount of second resin in the second prepreg sheet is larger than the amount of first resin in the first prepreg sheet on a per unit volume basis in an interface between the first prepreg sheet and the second prepreg sheet when the second prepreg sheet is stacked on the first prepreg sheet.
