<p>PURPOSE:To cure easily a thermosetting resin with which layers are impregnated, by passing an electric current through carbon fiber layers constituting reinforcing layers to heat the layers. CONSTITUTION:After a carbon fiber sheet (a) or a laminate (b) comprising carbon fiber sheets that is impregnated with a colloidal thermosetting resin (e.g. an epoxy resin) is placed on a mold 1, a glass fiber reinforcing layer (f) impregnated with a thermosetting resin is placed thereon, and further a carbon fiber sheet (a) impregnated with a colloidal thermosetting resin is placed thereon, the opposite ends of the carbon fiber sheets (a) are pinched by electric current feeding clips 2, and an electric current is passed to heat up the carbon fibers thereby curing the thermoplastic resin by the heat. A heating oven or heater for the mold is not required, and the curing can be easily effected. The present method can be applied to a hand lay-up method as well as a vacuum forming method, a pressure molding method, etc.</p> |
