An apparatus for producing a resin coated fiber composite of a rod shape, tubular-shape or plate shape comprises a plurality of first members having an annular shape with a semi-circular ring shaped internal surface, second members having a disc shape with a semicircular ring shaped external surface, first connectors for assembling the first members, second connectors for assembling the second members, an outer die member semi-assembled with the first members and connectors, an inner die member semi-assembled with the second members and connectors, a heater, an inlet nozzle and an outlet nozzle, a zigzag shaped tunnel formed between the inner and outer die members for providing a narrow flow path of the fiber filaments, and resin inlet ports to fill the molten resin in the zigzag shaped tunnel and pressurize the flow path of the fiber filaments. A process for preparing a resin coated fiber composite of a rod-shape, tubular-shape or plate-shape comprises steps of spreading fiber filaments by passing the fiber filaments through a first member having a convex-concave portion to prevent fracture of the fiber filaments, and sequentially tensioning through a series of first and second members all along a narrow flow path to maximize molten resin penetrating surface area, impregnating pressurized molten resin into the fiber filaments continuously by passing the fiber filaments through a series of the first and second members all along the narrow flow path of a zigzag shaped tunnel to maximize molten resin penetrating time, and wherein pressurization of the molten resin maximizes penetration of molten resin into pores of the fiber filaments and minimizes possibility of resin degradation, stranding the resin-coated fiber filaments through a final set of the first members having the convex-concave portion for strengthening the fiber filaments, and integrating and pultruding the resin-coated fiber filaments continuously by passing the fiber filaments all along the narrow flow path of the zigzag shaped tunnel to form a desired diameter through the outlet nozzle.
