Abstract:
A system and method for producing a uniform continuous fiber filament. The system and method include a fiber tow with an axial magnet attached to an end of the fiber tow, a polymer tube, and a radial magnet that fits around a circumference of the polymer tube. The radial and axial magnets are used to feed the fiber tow through the polymer tube using magnetic forces to create the uniform continuous fiber filament.
