To easily cut CFRP, a metal mold for CFRP component includes a stationary blade that stands still in contact with one surface of a CFRP material made of a carbon fiber reinforced plastic, and a moving blade arranged at a moving blade surface side of the CFRP material, the moving blade surface being a surface at an opposite side to a stationary blade surface, the stationary blade surface being a surface of a side where the stationary blade is positioned, and adapted to cut the CFRP material by being moved from the moving blade surface side to the stationary blade surface side and providing shear force to the CFRP material together with the stationary blade. |

1. A metal mold for a carbon fiber reinforced plastic component, comprising:
a stationary blade that is a blade standing still in contact with one surface of a material to be processed made of a carbon fiber reinforced plastic; a moving blade arranged at a moving blade surface side of the material to be processed, the moving blade surface being a surface opposite to a stationary blade surface, the stationary blade surface being a surface at a side where the stationary blade is positioned, and adapted to cut the material to be processed by being moved from the moving blade surface side to the stationary blade surface side and providing shear force to the material to be processed together with the stationary blade; a heating unit adapted to heat the material to be processed to raise a temperature of a cut portion in the material to be processed; and a pressing unit adapted to provide pressing force in a moving direction of the moving blade to the material to be processed, wherein, at the time the carbon fiber reinforced plastic is a thermosetting resin, the heating unit heats the cut portion in the material to be processed to be within a temperature range including a temperature of a glass transition point of the thermosetting resin, and in which a physical property of the material to be processed becomes to have a suitable value for heating, and the pressing unit provides the pressing force to the material to be processed at a time of cutting the material to be processed within a range from 3 to 10 MPa, both inclusive. |
