The present invention relates to a method of producing a coating liquid impregnated sheet-like reinforcing fiber bundle formed by applying a coating liquid to a sheet-like reinforcing fiber bundle that is unidirectionally arranged continuous reinforcing fibers long in one direction. The present invention provides a production method and a coating device of a coating liquid impregnated sheet-like reinforcing fiber bundle, wherein the method and device can effect continuous running without clogging of generated fuzz even at a high running speed and effect efficient impregnation of a coating liquid into the sheet-like reinforcing fiber bundle. The present invention relates to a method of producing a coating liquid impregnated sheet-like reinforcing fiber bundle, including allowing a sheet-like reinforcing fiber bundle, which is unidirectionally arranged reinforcing fibers, to pass substantially vertically downward through the inside of a coating section storing a coating liquid, whereby the method provides the sheet-like reinforcing fiber bundle with the coating liquid; wherein the coating section includes a liquid pool and a narrowed section which are in communication with each other; wherein the liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of the sheet-like reinforcing fiber bundle, and wherein the narrowed section has a slit-like cross-section and has a smaller cross-sectional area than the top side of the liquid pool.

Provided is a production method of an FRP precursor. The method includes: a pre-coating step of applying a resin varnish having a filler content of 5 vol % or less in a solid content thereof, to a sheet-shaped aggregate, and a melt-pasting step of melt-pasting a pair of resin films, each having a filler content of 30 vol % or more, to both surfaces of the aggregate, after the pre-coating step.

The present invention relates to a method for producing a unidirectional tape with a surface polymer layer, the method comprising the steps of a) providing an impregnation slurry comprising particles of a polymer, water, optionally a surfactant, optionally an organic carrying medium, optionally organic compounds and optionally surface active compounds, and providing a pressing tool having a surface profile structure, the surface profile structure having a surface roughness Ra of 1 to 20 μm, preferably of 2 to 10 μm, more preferably 3 to 7 μm, b) impregnating a unidirectional fiber layer comprising unidirectional fibers with the impregnation slurry to obtain an impregnated unidirectional fiber layer comprising the particles of the polymer, c) pressing at a surface of the impregnated unidirectional fiber layer with the surface profile structure to move at least some of the particles of the polymer within the impregnated unidirectional fiber layer onto the surface to form a surface polymer layer on the unidirectional fiber layer, and d) obtaining a unidirec

A ribbon yarn having an upper side and a lower side, filaments and at least one binder material, the binder material binding the filaments to one another and the upper side and/or the lower side of the ribbon yarn having a pressure-sensitive adhesive. The filaments of the ribbon yarn can consist only of one material or of different materials and they can be arranged in one layer or in multiple layers. The pressure-sensitive adhesive can be applied on the upper side and/or lower side of the ribbon yarn or can be a constituent of the binder material.

A resin bath device for wet winding provided herein includes a resin stirring bath and a resin impregnation bath, where a bottom of a side wall of the resin stirring bath is connected to the resin impregnation bath, two ingredient baths are provided at two ends of the resin stirring bath, and a stirring mechanism is arranged inside the resin stirring bath. A resin dipping roller is mounted at a middle of the resin impregnation bath where a pressure roller is mounted at tops of side walls; an electric heating coil is arranged inside a bottom wall of the resin impregnation bath, and an electric heating rod is arranged at an axis of the pressure roller; and wire guide rollers are mounted at two ends of the side wall of the resin impregnation bath.

Systems and methods are described where a volume receiving a liquid matrix and fibers at an inlet where opposing sides of the volume converge to form a gap and a moving surface in contact with the liquid matrix and the fibers and moving with respect to the liquid matrix and the fibers through the gap such that shear force is transferred to the liquid matrix and the fibers pushing the liquid matrix and the fibers forward through the gap, creating currents in the liquid matrix and increasing pressure. The increased pressure within the volume forms a barrier to entrained gases within the liquid matrix such that the entrained gases are inhibited from passing through the gap along with the liquid matrix and the fibers.
