Abstract

A method for molding a composite material in which a curved corner is formed between two planes by using a molding jig includes: shaping a laminated body in such a manner that a thickness of the laminated body is decreased from an outer side toward an inner side of the corner, by using the molding jig in which the angle formed by the two planes is a first bending angle, the laminated body including fiber sheets laminated so as to have the corner curved at the first bending angle; and shaping the laminated body in such a manner that the thickness is decreased from the outer side toward the inner side by curving the corner so as to form a second bending angle, by using the molding jig in which the angle formed by the two planes is the second bending angle smaller than the first bending angle.
