| titleOfInvention | Production method for prepreg, production method for prepreg tape, and production method for fiber reinforced composite material |
| abstract | Regarding a method for producing a prepreg that is obtained by applying a matrix resin to a fiber reinforced sheet, the present invention addresses the problem of providing a prepreg production method by which continuously travel can be performed without involving jamming of a generated fluff even when the travel speed is high, and by which a fiber reinforced sheet can be efficiently impregnated with a matrix resin. The production method for a prepreg comprises applying a matrix resin (2) to a fiber reinforced sheet (1a) by causing the fiber reinforced sheet (1a) to pass through the inside of a coating part (20) in which the matrix resin (2) is reserved, and further performing spray coating or curtain coating of discharging a liquid to a primary prepreg (1c) drawn out from the coating part (20), wherein: the coating part (20) is provided with a liquid reservoir section and a constriction section which are connected to each other; the liquid reservoir section has a portion the cross-sectional area of which continuously decreases along the travel direction of the fiber reinforced sheet (1a); and the constriction section has a slit-shaped cross section, and has a cross-sectional area smaller than that of the upper surface of the liquid reservoir section. |
