PROBLEM TO BE SOLVED: To form a sharply bent part by stably shaping without deformation due to damage or spring back by separating reinforcing fiber along a ridge of a mold shape of a fiber-reinforced sheet before the molding step of a profile section. SOLUTION: An end of a rod-like member 3 having the end including a radius of curvature of, for example, 3 mm or less is brought into contact with a site to be a ridge of a profile section of a fiber-reinforced sheet 1 on a table 2, and the sheet 1 is moved in a lengthwise direction. The fiber 3 and table 2 become a means for forming a flute for forming the ridge of the profile section composite material at the sheet 1. When the end of the material 3 is pressed to the sheet 1, a surface of the table 2 having elasticity is recessed, and the sheet 1 is drawn, and hence a flute 4 is formed along the moving direction at a position to become the ridge of the section of the sheet 1. Thereafter, it enters the molding step. |
