摘要: A process for producing a resin-impregnated fiber bundle includes an unwinding step in which a resin-unimpregnated fiber bundle is unwound, a resin impregnation step in which the fiber bundle is passed through an impregnation bath filled with a resin, and an impregnation acceleration step in which after the resin impregnation step, the resin is permeated into the fiber bundle, at least the impregnation acceleration step being performed in a decompression space having a pressure lower than atmospheric pressure. It is possible to produce a resin-impregnated fiber bundle using a decompression space for which decompression can be achieved with a simple device and in which the airtightness is easy to maintain and which has been configured so as to result in satisfactory working efficiency.
