PURPOSE:To perform the cure of a resin efficiently and enhance a bond strength between fibers and the resin, by impregnating the thermosetting resin to the texture composed of the reinforcing fibrous thread of a volume electric resistivity ranging 10<-4>-10<-1>OMEGA.cm, then curing the resin by applying an electric current to said texture and heating. CONSTITUTION:After the bundle 1 of reinforcing fibers which is an electric heat generating object is embedded with a thermostting resin 2 and its circumference is covered with the resin 2, both end parts 3, 3' of the bundle 1 to which the resin does not stick are held by the clamps 4, 4' connected to the lead wires and when an electric current is applied to the bundle 1, it is heated and the cure of the resin proceeds. After a lapse of predetermined time the composite material which has an excellent compatibility with the reinforcing resin can be obtained perfectly and uniformly. Thereby, the cure of the resin can be done efficiently by a uniform heat treatment and the molded article having excellent bonding properties between the reinforcing fibers and the matrix resin can be obtained.
