Coating-liquid-impregnated fiber-reinforced fabric, sheet-shaped integrated object, prepreg, prepreg tape, and method for manufacturing fiber-reinforced composite material

A method of producing a coating liquid-impregnated sheet-shaped reinforcing fiber fabric, comprising:

• allowing a sheet-shaped reinforcing fiber fabric to pass substantially vertically downward through the inside of a coating section storing a coating liquid to provide said reinforcing fiber fabric with said coating liquid;
• wherein said coating section includes a liquid pool and a narrowed section which are in communication with each other;
• wherein said liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of said reinforcing fiber fabric;
• wherein said narrowed section has a slit-shaped cross-section and has a smaller cross-sectional area than the top side of said liquid pool;
• wherein the vertical height of said portion whose cross-sectional area decreases continuously in said liquid pool is 10 mm or more, and
• wherein said coating section further comprises, in said liquid pool, a width regulation mechanism for regulating the width of said reinforcing fiber fabric, wherein the relationship between the width (W) of said reinforcing fiber fabric immediately under said narrowed section and the width (L2) regulated by said width regulation mechanism at the lower end of said width regulation mechanism satisfies L2≤W+10 (mm).
