PURPOSE:To obtain a die light in weight, excellent in durability, and having high rigidity by reinforcing a shell, formed by metal spraying, by a layer of fiber- reinforced thermosetting resin and further backing it up by a composition of thermosetting resin. CONSTITUTION:A metallic layer of 0.1-40mm. thickness is formed on the surface of a prototype by spraying a metal, after providing releasing treatment to the surface of the prototype having a shape inverse to the surface shape of a die. A layer of fiber-reinforced thermosetting resin of >=0.5mm. thickness is formed on the metallic layer, and further a composition of themosetting resin is filled up in other parts, to complete a shape of the whole body. Then the die is obtained by releasing it from the prototype. Further, the layer of fiber-reinforced thermosetting resin is constituted of a carbon fiber and a composition of thermosetting resin. |
