PROBLEM TO BE SOLVED: To provide a mold for producing FRP filaments in which resin- impregnated fibers can be molded and cured easily, the surface properties of the fibers are good, and shapes are possible in the continuous production of the filaments by a pultrusion method and a method for producing the filaments. SOLUTION: In a method for producing FRP filaments continuously in which fibers are impregnated with a resin liquid, the rein-impregnated fibers are introduced into a mold D, the resin is cured in the mold and/or after passage through the mold, the mold D comprises plate-shaped molds 2-5 mm in thickness and is composed of a group of the plate-shaped molds in which they are connected together so that cavities formed in them communicate with each other, a tapered opening part is formed on the side of an introduction port for the fibers in each plate-shaped mold, and the opening part is connected to the cavity of the plate-shaped mold. |
