Abstract: A method for deriving the position of a pushing roll, applied even when there is a difference between the actual processed shape and a theoretical solution (a numerical analysis solution) due to changes in a state of a processing machine or the bending characteristic of the material to be processed. The rolls have a pyramid-like shape, and the operation amount of a pushing roll is changed while continuously feeding a material, thereby bending the material. Also, for each position of the fixed pushing roll, the radius of curvature of the material is measured and the bending characteristic is grasped in advance. From the design shape, the radius of curvature and the operation amount for bringing the pushing roll into contact are obtained. The operation amount of the pushing roll is then determined.

Abstract: A method for producing a molded article of a fiber-reinforced plastic include molding a fiber-resin mixture containing an inorganic reinforcing fiber and a thermosetting resin under heat and pressure. The elapsed time since the thermosetting resin reached a molding temperature at which a hardening reaction proceeds is measured, the loss angle ? of the thermosetting resin is measured in a dynamic viscoelasticity measurement, and the relationship between the elapsed time and the loss angle ? is evaluated to calculate the range of the elapsed time, within which the loss angle ? is 0.55 to 1.57 rad after the loss angle ? reached the maximum value, as the pressurization start range. The fiber-resin mixture is heated to the molding temperature and pressure application to the fiber-resin mixture is started within the pressurization start range, to obtain the molded article of the fiber-reinforced plastic.
