Abstract

PURPOSE:To enable the continuous FRTP prepreg with high quality to be formed, while it has no remaining bubbles and is uniformly and surely impregnated with resin by a method in which the width of a continuous fiber bundle is expanded before it is dipped in molten resin, and the width of the continuous fiber bundle is reduced before it comes out of the molten resin bath. CONSTITUTION:Three columnar parallel bars 24a-24c are provided in the introducing part 29 of the passing part Ta of a fiber bundle in the direction crossing the advancing direction of a tow, and the fiber bundle 1 is alternately laid across said bars, whereby the running locus bent in dog leg shape is formed. A regulation part 28 introducing molten resin 12 into the passing part Ta is formed downstream of these parallel bars 24a-24c. Further downstream thereof, while a parallel bar 25 and bundling bars 26a, 26b are provided in the direction crossing the advancing direction of the tow 1, a nozzle part 31 is formed. Further downstream of the nozzle part 31, a cooler 22 and the take-up machine 27 for a prepreg 1C are provided, and the prepreg 1C is continuously fed to a wind-up machine 23.
