Coating solution-impregnated reinforced fiber fabric, sheet-like integral body, prepreg, prepreg tape, and manufacturing method of fiber-reinforced composite material

摘要

The present invention relates to a method for manufacturing a reinforcing fiber fabric impregnated with a coating solution in which a coating solution is applied to a reinforcing fiber fabric, and continuous running is possible without clogging the generated fluff even when the running speed is high, and the coating solution is efficiently applied to the reinforcing fiber fabric In order to provide a method for producing a coating liquid-impregnated reinforcing fiber fabric that can be well impregnated, the reinforcing fiber fabric 1a is formed inside the application portion 20 in which the coating liquid 2 is stored, the reinforcing fiber fabric; A method for producing a coating solution-impregnated reinforcing fiber fabric (1b) in which the coating solution (2) is applied to the reinforcing fiber fabric (1a) by passing it substantially vertically downward, wherein the coating unit 20 includes a liquid pool communicating with each other and a constriction, wherein the liquid pool has a portion whose cross-sectional area continuously decreases along the running direction of the reinforcing fiber fabric 1a, the constriction has a slit-like cross-section, and has a cross-sectional area smaller than the upper surface of the liquid pool, The vertical height of the portion where the cross-sectional area continuously decreases in the liquid pool is 10 mm or more.
