Device and method for manufacturing impregnated fiber bundle

A device for manufacturing impregnated fiber bundle, comprising:

• a feeding unit including a fiber bundle wheel and a feeding wheel assembly, the fiber bundle wheel supplying a fiber bundle to the feeding wheel assembly;
• a surface roughening unit connected to the feeding unit, and including a negative pressure chamber, wherein the fiber bundle is fed into the negative pressure chamber by the feeding wheel assembly, an electric arc generator is disposed in the negative pressure chamber to continuously produce discharge gas to form a plurality of cavities in an outer surface of the fiber bundle, and wherein the negative pressure chamber creates negative pressure inside the fiber bundle;
• a resin molding unit connected to the surface roughening unit, and including an output device and a resin input device which communicate with each other, the output device including an output pipeline for transporting the fiber bundle which has been formed with the cavities, the resin input device including an input pipeline which communicates with the output pipeline, wherein resin is fed from the input pipeline into the output pipeline by a continuous screw in a high pressure manner, and infiltrates into the fiber bundle to form an outer resin layer on the outer surface of the fiber bundle, the cavities increase bonding force and bonding area between the fiber bundle and the resin, the output device including an output hole for outputting a resin impregnated fiber bundle;
• a semi-cured molding unit connected to the resin molding unit to receive the resin impregnated fiber bundle coming from the output device, the semi-cured molding unit enables the resin inside and outside the resin impregnated fiber bundle to be semi-cured by controlling temperature and pressure inside the semi-cured molding unit;
• and
• a reeling unit connected to the semi-cured molding unit to reel up the resin impregnated fiber bundle which is to be woven into a fabric.
