METHOD OF MANUFACTURING FOR THERMOPLASTIC TAPE WITH IMPREGNATED CONTINUOUS CARBON FIBER

摘要

PURPOSE: A molding method of a thermoplastic resin tape with continuous phase carbon fiber is provided to evenly impregnate the continuous phase carbon fiber with thermoplastic resin by evenly dispersing continuous phase carbon fiber in a carbon fiber bundle, one strand at a time. CONSTITUTION: A molding method of a thermoplastic resin tape with continuous phase carbon fiber comprises the steps of: unraveling a roving (1) rolled with a continuous phase carbon fiber bundle by a spreading roller (3), one strand at a time; coating the thermoplastic resin on the surface of continuous phase carbon fiber by passing the unraveled continuous phase carbon fiber through thermoplastic resin powder and irradiating microwave; and passing continuous phase carbon fibers coated with thermoplastic resin powder through the vacuum compression (6) while pressuring the carbon fibers under the vacuum condition to produce a tape integrated with continuous phase carbon fibers impregnated with thermoplastic resin.
