Zusammenfassung: | PURPOSE: A method and a device for manufacturing one-way prepregs containing uniform contents of fibers are provided to manufacture prepreg without content deviation because the fluidity of resin in both ends that do not receive heat is diminished while a resin film and carbon fiber pass through a heating plate having a narrow width. CONSTITUTION: A method for manufacturing one-way prepregs containing uniform contents of fibers is as follows. A resin of a resin film penetrates through impregnation rollers(50) after the upper and lower surfaces of the fiber is wrapped with resin films(200), thereby being impregnated on the upper and lower surfaces. The resin film and fibers pass through the heating plate and impregnation rollers after heating plate is formed to be relatively narrower than the resin film and fibers passing the upside of the heating plate to prevent both ends of the resin film from being heated. |
