Document Type and Number:
WIPO Patent Application WO/2020/040151
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for producing a coating-liquid-containing reinforcing fiber tape in which fluff generation is suppressed and continuous production without clogging by fluff is made possible, and furthermore in which it is possible to impregnate the reinforcing fiber tape with the coating liquid efficiently and to increase the production speed. The main object of the present invention is a method for producing a coating-liquid-containing reinforcing fiber tape in which a reinforcing fiber tape having a tape width of 3-30 mm is passed through the inside of an application part in which the coating liquid is stored to apply the coating liquid to the reinforcing fiber tape, wherein the application part comprises a liquid reservoir part and a narrowed part that are in communication with each other, the liquid reservoir part has a portion in which the cross-sectional area decreases continuously along the running direction of the reinforcing fiber tape, the narrowed part has a slit-shaped cross-section and has a cross-sectional area smaller than that of an upper surface of the liquid reservoir part, and the width coefficient of variation (CV) of the coating-liquid-containing reinforcing fiber tape drawn out from the narrowed part is 5% or less.
