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

The invention enhances the production efficiency in the production of prepreg by allowing the arrangement property and rectilinearity of reinforcing fibers to be well maintained, allowing the basis weight uniformity of an applied resin to be good, and further allowing a high line speed and suppression of contamination in the process to be achieved. The invention provides a method of producing a prepreg, which includes: discharging a molten resin from a discharge portion; introducing the discharged resin by an air flow; and capturing the discharged resin on a reinforcing fiber sheet conveyed continuously, wherein a key point is that the discharged resin is captured in a region in which the reinforcing fiber sheet is conveyed substantially in planar form.
