  • Patent number: 5932050
    Abstract: A spray device is prepared has a plurality of nozzles each of which has a capillary tube surrounded by a gas discharge pore at the end of the nozzle. A molten resin liquid is blown out to a reinforcing fiber from the capillary tube by heated air stream discharged through the gas discharge pore, so that a binder resin layer is formed on the reinforcing fiber. Following this, a resin-permeable supporting sheet and then a back-up sheet are applied to the binder resin layer side of the reinforcing fiber, and a releasing sheet is applied to the other side of the reinforcing fiber. The thus obtained superposed layers are pressed to adhere the reinforcing fiber, the supporting fiber and the back-up sheet to each other.
