PRODUCTION METHOD FOR PREPREG, AND PRODUCTION METHOD FOR FIBER-REINFORCED COMPOSITE MATERIAL

The purpose of the present invention is to produce a prepreg such that the arrangement and straightness of reinforcing fibers are favorably maintained, such that the density of a coating resin is favorably uniform, and such that production efficiency is increased by suppressing high line speeds and suppressing contamination during the production process. The present invention is a prepreg production method in which a molten resin is discharged from a discharge part, is guided by an airflow, and collects on a continuously conveyed reinforcing-fiber sheet. The discharged resin collects in an area in which the reinforcing-fiber sheet is conveyed so as to be substantially planar.
