PURPOSE:To make a pressing device unnecessary and to simplify the structure of a heat treating furnace by winding heat resistant fibers having a negative coefft. of linear expansion around a molded body of carbon fibers impregnated with a resin binder to apply pressure. CONSTITUTION:Carbon fibers are coated or impregnated with a resin binder and molded to obtain a molded body. Heat resistant fibers having high tensile strength and a negative coefft. of linear expansion, e.g., carbon fibers or aramide fibers are directly or indirectly wound around the molded body to apply pressure. The molded body is then heat-treated under the pressure. |
